Description

Technical Field

[0001] This application relates to the field of electromagnetic wave orbital angular momentum (OAM) quantum state technology, and in particular to a vortex microwave quantum information transmission system and method. Background Technology

[0002] Orbital angular momentum (OAM) is linearly independent of the dimension of electric field strength, and can be regarded as a new dimension for wireless transmission. Therefore, OAM can increase information transmission capacity based on Shannon theory. Depending on the composition, OAM can be divided into vortex beams and vortex microwave quanta. Vortex beams are usually generated by antenna arrays or dedicated antennas, while vortex microwave quanta are generated by high-speed moving electrons with relativistic effects. The fact that vortex microwave quanta can transmit information and improve spectral efficiency has been confirmed.

[0003] In related technologies, a diffraction grating method is used to transfer the OAM of vortex microwave quanta to electrons at the receiving end. After diffraction, the electrons carrying the OAM will form different diffraction patterns on the fluorescent screen. Based on the diffraction patterns, the mode detection of vortex microwave quanta can be realized.

[0004] However, this method requires the use of diffraction patterns on the fluorescent screen at the receiving end to achieve modal detection, which is a relatively complex process that urgently needs to be addressed. Summary of the Invention

[0006] To achieve the above objectives, a first aspect of this application proposes a vortex microwave quantum information transmission system, comprising a transmitter and a receiver. The transmitter includes a vortex microwave quantum feed module, a reflector lens antenna combination module, and an interaction module between a ray tube and a reflector lens antenna.

[0009] The interaction module between the ray tube and the reflector lens antenna is used to model the ray tube based on the ray tube gain and a preset quaternion strategy to obtain a preset ray tube model, and to solve the time delay of the ray tube in the incident medium based on a preset quantum electrodynamic strategy. Based on the time delay, the refractive index of the ray tube is obtained, and the ray tube path through which the at least two modes of vortex microwave quantum passes is obtained according to the refractive index.

[0010] The information recovery module is used to obtain the landing region of the at least two modes of vortex microwave quantum according to the ray tube path through which the vortex microwave quantum passes, perform mode sorting of the at least two modes of vortex microwave quantum based on the power measurement strategy and the landing region, and perform information recovery of the at least two modes of vortex microwave quantum based on the preset serial interference strategy to obtain the original information.

[0022] A refractive index determination unit is used to solve for the time delay of the X-ray tube in the incident medium based on the preset quantum electrodynamic strategy, and to obtain the refractive index of the X-ray tube based on the time delay.

[0023] According to one embodiment of this application, the information recovery module includes:

[0024] A mode sorting unit is used to obtain the falling region of the at least two modes of vortex microwave quanta based on the properties of the at least two modes of vortex microwave quanta, and to distinguish the at least two modes of vortex microwave quanta based on the falling region.

[0025] A power measurement unit is used to detect the power of the at least two modes of vortex microwave quanta falling into the region according to a power measurement strategy, so as to achieve the sorting of the at least two modes of vortex microwave quanta.

[0026] An information recovery unit is used to recover information from the at least two modes of vortex microwave quantum based on a preset serial interference strategy.

[0027] According to one embodiment of this application, the vortex microwave quantum is an electron rotating at high speed in a gyroscope, and the gyroscope is located at the focal point of the reflector antenna.

[0028] According to one embodiment of this application, the vortex microwave quantum is a vortex microwave quantum across the entire frequency band.

[0029] According to one embodiment of this application, the preset quaternion strategy is as follows:

[0030]

[0031] Wherein, l represents the OAM mode of the ray tube. This is the vector representation of the ray tube in three-dimensional space.

[0032] According to one embodiment of this application, the refractive index is:

[0034] Where c is the speed of light, τ i→f p is the time delay. p denoted as , where is the proportion of interfering electron photons in the incident photon sequence, and d is the distance that a vortex microwave quantum must travel to encounter an electron in an atom.

[0035] The vortex microwave quantum information transmission system proposed in this application transmits vortex microwave quanta at the feed position through a vortex microwave quantum feed module, and further uses a reflective lens antenna combination module to ensure that vortex microwave quanta of different modes have different transmission paths. The ray tube is modeled through an interaction module between the ray tube and the reflective lens antenna, and the refractive index of the ray tube is obtained by solving the time delay of the ray tube in the incident medium. An information recovery module performs mode sorting of vortex microwave quanta of different modes based on the landing regions of the vortex microwave quanta of different modes, and recovers the information from the vortex microwave quanta of different modes. Thus, by using a combination of reflective antenna and lens antenna to achieve mode sorting and complete the information transmission of vortex microwave quanta, the system solves the problem of difficult mode sorting of vortex microwave quanta at the receiving end in traditional vortex microwave quantum communication transmission, ultimately achieving efficient and accurate information transmission.

[0036] To achieve the above objectives, a second aspect of this application proposes a vortex microwave quantum information transmission method, employing the vortex microwave quantum information transmission system as described in the first aspect embodiment. The method includes the following steps:

[0037] The vortex microwave quantum feed module emits the vortex microwave quantum at the feed position based on the preset mode keying strategy or the preset mode information transmission multiplexing strategy.

[0038] The reflective lens antenna combination module uses the preset geometric relationship and the properties of the vortex microwave quantum to perform mode division of the vortex microwave quantum, so as to distinguish the vortex microwave quantum of different modes and maximize the difference in the position of at least two modes of vortex microwave quantum falling into the receiving end region.

[0039] The ray tube and the reflector lens antenna interaction module are used to model the ray tube based on the ray tube gain and the preset quaternion strategy to obtain the preset ray tube model. The time delay of the ray tube in the incident medium is solved based on the preset quantum electrodynamic strategy. The refractive index of the ray tube is obtained based on the time delay. The ray tube path through which the at least two modes of vortex microwave quantum passes is obtained based on the refractive index.

[0040] The information recovery module obtains the landing regions of the at least two modes of vortex microwave quantum based on the ray tube path traversed by the vortex microwave quantum. Based on the power measurement strategy and the landing regions, the at least two modes of vortex microwave quantum are sorted by mode. Based on the preset serial interference strategy, the information of the at least two modes of vortex microwave quantum is recovered to obtain the original information.

[0041] The vortex microwave quantum information transmission method proposed in this application solves the problem of difficult vortex microwave quantum mode selection at the receiving end in the traditional vortex microwave quantum communication transmission process by using a combination of reflective surface antenna and lens antenna to achieve mode sorting and complete vortex microwave quantum information transmission, ultimately achieving efficient and accurate information transmission.

[0053] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0054] The following description, with reference to the accompanying drawings, describes a vortex microwave quantum information transmission system and method according to embodiments of this application.

[0055] Before introducing the vortex microwave quantum information transmission system proposed in the embodiments of this application, let's first introduce the relevant technical background.

[0056] It has been confirmed that vortex microwave quanta can be generated by electrons in a magnetic field under relativistic effects, which lays the foundation for the generation of vortex microwave quanta in the system. At the transmitting end of the vortex microwave quantum, encoded information is transmitted by emitting vortex microwave quantum in different modes in a keying manner; at the receiving end of the vortex microwave quantum, mode sorting of the vortex microwave quantum can be achieved by identifying the diffraction pattern passing through the grating.

[0057] For vortex microwave quantum quantum, achieving mode detection is fundamental to realizing quantum information transmission. The diffraction grating method transfers the OAM (Optical Aspect-Oriented Motion) of the vortex microwave quantum to electrons at the receiving end. These electrons, carrying the OAM, form different diffraction patterns on a fluorescent screen after diffraction. Based on these diffraction patterns, vortex microwave quantum mode detection can be achieved. Therefore, a vortex microwave quantum OAM detection device has been proposed.

[0058] However, achieving modal detection using diffraction gratings and the diffraction pattern on the receiver's fluorescent screen is extremely complex. Further research is needed to establish alternative methods for modal detection and information transmission. Simultaneously, the prediction and calculation of electromagnetic wave propagation are fundamental to solving the propagation laws of vortex microwave quanta in a combined reflector and lens antenna system. Using ray tracing methods based on geometrical optics (GO) and uniform diffraction theory (UTD), calculations can be performed in specific electromagnetic environments to quickly and concisely obtain the propagation path of electromagnetic waves and calculate the electric field intensity at specific spatial locations. Therefore, ray tracing, as an important method in computational electromagnetics, can be combined with other methods for analyzing and solving OAM (Optical Aspect-Oriented Motion).

[0059] The following describes the vortex microwave quantum information transmission system proposed in the embodiments of this application.

[0060] Figure 1 This is a block diagram of a vortex microwave quantum information transmission system according to an embodiment of this application.

[0061] like Figure 1 As shown, the vortex microwave quantum information transmission system 10 includes a transmitter 1 and a receiver 2. The transmitter 1 includes a vortex microwave quantum feed module 100, a reflector lens antenna combination module 200, and a ray tube and reflector lens antenna interaction module 300. The receiver 2 includes an information recovery module 400. The vortex microwave quantum feed module 100 transmits vortex microwave quanta at the feed position based on a preset mode keying strategy or a preset mode information transmission multiplexing strategy. The reflector lens antenna combination module 200 performs mode division on the vortex microwave quanta according to a preset geometric relationship and the properties of the vortex microwave quanta, to distinguish between vortex microwave quanta of different modes, and to minimize the difference in the positions where at least two modes of vortex microwave quanta fall into the receiver region. The interaction module 300 between the ray tube and the reflector lens antenna is used to model the ray tube based on the ray tube gain and a preset quaternion strategy to obtain a preset ray tube model. It also solves for the time delay of the ray tube in the incident medium based on a preset quantum electrodynamic strategy, obtains the refractive index of the ray tube based on the time delay, and obtains the ray tube path of at least two modes of vortex microwave quanta based on the refractive index. The information recovery module 400 is used to obtain the landing region of at least two modes of vortex microwave quanta based on the ray tube path of the vortex microwave quanta, performs mode sorting of at least two modes of vortex microwave quanta based on a power measurement strategy and the landing region, and performs information recovery of at least two modes of vortex microwave quanta based on a preset serial interference strategy to obtain the original information.

[0062] Specifically, the vortex microwave quantum feed module 100 can transmit vortex microwave quanta at the feed location based on a preset mode keying strategy (switching transmission of vortex microwave quanta of different modes) or a preset mode information transmission multiplexing strategy (allowing multiple vortex microwave quanta to be transmitted in the same channel); the reflector lens antenna combination module 200, through precise physical design, considers preset geometric relationships and the properties (OAM characteristics) of vortex microwave quanta to perform mode division of vortex microwave quanta. Different modes of vortex microwave quanta have different OAM values, which makes them exhibit unique differences in spatial distribution and phase structure, thus obtaining vortex microwave quanta of multiple modes; the ray tube and reflector lens antenna interaction module 300 can adopt a vortex microwave based on the ray tube. The wave quantum transmission analysis method establishes a preset ray tube model and solves the interaction between vortex microwave quanta and matter. First, the ray tube is represented by the ray tube gain and a preset quaternion strategy to obtain the preset ray tube model. Then, the time delay of the ray tube in the incident medium is solved by a preset quantum electrodynamic strategy to obtain the refractive index of the ray tube. Based on the refractive index, the path of the vortex microwave quantum after passing through the lens antenna (i.e., the ray tube path traversed by the vortex microwave quantum) can be obtained. The information recovery module 400 can obtain the different regions near the focal point of the receiver by different modes of vortex microwave quanta through a power measurement strategy, thereby realizing mode sorting of vortex microwave quanta. Then, a preset serial interference cancellation strategy is used to realize the detection and recovery of information at the receiver to obtain the original information.

[0063] This application embodiment uses a combination of reflective surface antenna and lens antenna to complete the transmission of vortex microwave quantum information, and solves the problem of reflection and transmission of vortex microwave quantum on the surface of the medium. This can effectively reduce the complexity of the vortex microwave quantum information transmission system and realize the sorting of vortex microwave quantum of different modes.

[0064] To facilitate understanding, the following will be combined with Figure 2 The vortex microwave quantum feed module 100, the reflector lens antenna combination module 200, the X-ray tube and reflector lens antenna interaction module 300, and the information recovery module 400 are described in detail respectively.

[0065] Alternatively, in some embodiments, such as Figure 2 As shown, the vortex microwave quantum feed module 100 includes: an electron cyclotron pulse unit 101, a vortex microwave quantum feed unit 102, and an information transmission unit 103. The electron cyclotron pulse unit 101 generates vortex microwave quanta; the vortex microwave quantum feed unit 102 provides signal input to the reflector antenna and displays the emission position of the vortex microwave quanta; the information transmission unit 103 transmits vortex microwave quanta based on a preset mode keying strategy and a preset mode information transmission multiplexing strategy.

[0066] In some embodiments, the vortex microwave quantum is an electron rotating at high speed in a gyroscope, which is located at the focal point of the reflector antenna.

[0067] Specifically, such as Figure 2 As shown, the electron cyclotron pulse unit 101 can generate vortex microwave quanta. That is, electrons undergoing high-speed cyclotron motion in the cyclotron can generate vortex microwave quanta under relativistic effects. Since vortex microwave quanta are different from vortex beams radiated by electrons moving at high speed in the cyclotron, they can be regarded as wave packets with vortex phase. Under the action of relativistic effects, high-speed electrons may interact with the electromagnetic field in the cyclotron, resulting in energy exchange. This energy exchange is manifested in the form of microwave quanta, and further generates vortex microwave quanta; vortex microwave... The quantum feed unit 102 provides signal input to the reflector antenna and serves as the transmission position for vortex microwave quanta. Specifically, the vortex microwave quantum feed (i.e., gyrotron) is positioned at the focal point of the reflector (i.e., parabolic) antenna. The information transmission unit 103 can transmit vortex microwave quanta based on a preset mode keying strategy and a preset mode information transmission multiplexing strategy. The vortex microwave quanta are keyed by switching between different modes (e.g., mode 0 and mode 1). Multiplexing transmission is achieved by adjusting the amplitude and phase of the vortex microwave quanta and simultaneously transmitting different modes. For example, the electron gyrotron pulse unit 101 can be implemented by adding a high voltage and a magnet to the electron gyrotron. The vortex microwave quantum feed unit 102 places the vortex microwave quantum generator at the focal point of the reflector antenna. The information transmission unit 103 can transmit information by switching between vortex microwave quantum mode 0 and mode 1.

[0068] Understandably, the pre-defined mode keying strategy determines how information is encoded into different vortex microwave quantum modes. For example, mode 0 and mode 1 are mapped to 0 and 1 in binary information, respectively. At the transmitting end, the vortex microwave quantum is precisely controlled to switch from one mode to another according to the sequence of information to be transmitted, thereby achieving information encoding. The pre-defined mode information transmission multiplexing strategy allows the simultaneous transmission of vortex microwave quantum modes of different modes, realizing the multiplexing transmission of information. This multiplexing strategy can be achieved by adjusting the amplitude and phase of the vortex microwave quantum. Through a carefully designed transmission system and modulation technology, it can be ensured that vortex microwave quantum modes of different modes propagate in space without interference and are correctly decoded at the receiving end.

[0069] Optionally, in some embodiments, the vortex microwave quantum is a vortex microwave quantum across the entire frequency band.

[0070] In other words, when vortex microwave quanta are considered as vortex microwave quanta across the entire frequency band, it means that these quantum states cover all possible frequency ranges of the microwave spectrum. In quantum communication, using vortex microwave quanta across the entire frequency band can enhance the transmission efficiency and robustness of information. Different frequency bands have different transmission characteristics and channel conditions. By utilizing vortex microwave quanta across the entire frequency band, the optimal frequency band can be selected to adapt to different scenarios and environments, thereby improving the performance and stability of the communication link.

[0071] Alternatively, in some embodiments, such as Figure 2 As shown, the reflector-lens antenna combination module 200 includes: a reflector antenna unit 201, a reflector antenna and lens antenna combination unit 202, and a lens antenna unit 203. The reflector antenna unit 201 is used to control the parallel transmission of at least two modes of vortex microwave quanta along a preset transmission axis; the reflector antenna and lens antenna combination unit 202 is used to differentiate the transmission paths of at least two modes of vortex microwave quanta; and the lens antenna unit 203 is used to transmit at least two modes of vortex microwave quanta in different directions.

[0072] Specifically, such as Figure 2 As shown, vortex microwave quanta emitted from the focal point of the reflector antenna first illuminate the reflector antenna of the reflector antenna unit 201. After reflection by the reflector antenna, at least two modes of vortex microwave quanta are emitted parallel to the reflector surface along a preset transmission axis and reach the lens antenna of the lens antenna unit 203. The lens antenna is composed of various microwave dielectric materials, and different dielectric materials have different refractive indices. When at least two modes of vortex microwave quanta pass through the lens antenna composed of microwave dielectric materials, the vortex microwave quanta of different modes will achieve different transmission directions due to the difference in refractive index of the dielectric materials, thus forming different transmission paths. The reflector antenna in the reflector antenna and lens antenna combination unit 202 can realize the parallel incident lens of vortex microwave quanta. The lens antenna combination can lay the foundation for mode sorting at the receiving end. Thus, the reflector antenna and lens antenna combination unit 202 jointly realize the path differentiation of vortex microwave quanta of different modes, avoiding interference and confusion between modes.

[0073] Alternatively, in some embodiments, such as Figure 2As shown, the interaction module 300 between the ray tube and the reflector lens antenna includes: a ray tube model building unit 301, a ray tube path tracing and solving unit 302, and a refractive index determination unit 303. The ray tube model building unit 301 is used to model the ray tube based on the ray tube gain and a preset quaternion strategy to obtain a preset ray tube model. The ray tube path tracing and solving unit 302 is used to determine the ray tube passing through the receiving end based on a preset geometric optics strategy and to mark the ray tube paths traversed by at least two modes of vortex microwave quantum. The refractive index determination unit 303 is used to solve for the time delay of the ray tube in the incident medium based on a preset quantum electrodynamics strategy, and to obtain the refractive index of the ray tube based on the time delay.

[0074] Among them, the X-ray tube gain is used to represent the intensity of the X-ray tube, and the preset quaternion strategy represents the mode of the X-ray tube and its position in three-dimensional space.

[0075] Specifically, such as Figure 2 As shown, the object of the ray tube model building unit 301 is the incident, emitted, and refracted vortex microwave quanta. Based on the ray tube gain and a preset quaternion strategy, the ray tube is modeled to obtain the preset ray tube model. The gain calculation method is obtained by calculating the interaction between the vortex microwave quanta and the microscopic particles in the medium. The ray tube path tracing and solution unit 302 can use a preset geometric optics strategy (such as the mirror method) to determine all ray tubes passing through the receiving end. There may be several paths from the ray tube generated at the transmitting end through the transmission environment to the receiving end. All paths traversed by the vortex microwave quanta are marked and mathematically represented to obtain a complete ray tube model. The tube path set; the refractive index determination unit 303 adopts a preset quantum electrodynamic strategy (the theory for studying the quantum properties of electromagnetic interactions). By solving the time delay of the ray tube in the medium, the refractive index of the ray tube after it is incident on the medium is obtained. For example, tools such as wave functions, perturbation theory and Fresnel refraction formula are used to analyze the propagation process of vortex microwave quanta in the medium. By solving these equations, the time delay of the ray tube propagation in the medium can be obtained. This time delay reflects the result of the interaction between the vortex microwave quanta in the ray tube and the medium, thus indirectly reflecting the refractive index characteristics of the medium. Therefore, based on the time delay, it can be used to calculate the refractive index of the ray tube.

[0076] Optionally, in some embodiments, the preset quaternion strategy is:

[0077]

[0078] Where l represents the OAM mode of the ray tube. This represents the vector representation of the ray tube in three-dimensional space.

[0079] Understandably, in vortex microwave quantum communication, quaternions can be used to accurately represent and track the rotational state and direction changes of vortex microwave quanta. Traditional electromagnetic methods may face some challenges in dealing with vortex microwave quantum communication, especially in modeling and describing complex three-dimensional spatial rotation and phase structures. However, the embodiments of this application introduce a quaternion representation method. Through its unique mathematical properties and representation method, it can solve the problem that traditional electromagnetic methods cannot perform channel modeling for vortex microwave quantum communication transmission, and provide a more accurate mathematical basis for vortex microwave quantum communication channel modeling.

[0080] Optionally, in some embodiments, the refractive index is:

[0081]

[0082] Where c is the speed of light, τ i→f For time delay, p p denoted as , where is the proportion of interfering electron photons in the incident photon sequence, and d is the distance that a vortex microwave quantum must travel to encounter an electron in an atom.

[0083] Alternatively, in some embodiments, such as Figure 2 As shown, the information recovery module 400 includes: a mode sorting unit 401, a power measurement unit 402, and an information recovery unit 403. The mode sorting unit 401 is used to obtain the landing regions of at least two modes of vortex microwave quanta based on the properties of at least two modes of vortex microwave quanta, and to distinguish between at least two modes of vortex microwave quanta based on the landing regions. The power measurement unit 402 is used to detect the power within the landing regions of at least two modes of vortex microwave quanta according to a power measurement strategy, thereby sorting at least two modes of vortex microwave quanta. The information recovery unit 403 is used to recover information from at least two modes of vortex microwave quanta based on a preset serial interference strategy.

[0084] Specifically, such as Figure 2As shown, the mode sorting unit 401 can distinguish between different modes of vortex microwave quanta by utilizing the property that vortex microwave quanta of different modes fall into different regions near the antenna feed of the receiving end reflector. The power measurement unit 402 performs mode sorting of vortex microwave quanta based on the power measurement strategy and the falling regions of at least two modes of vortex microwave quanta. That is, power measurement is performed in different regions. Since vortex microwave quanta of different modes have different distribution characteristics in space, their power will also be different in different regions. By comparing the power measurement results of each region, vortex microwave quanta of different modes can be identified. In vortex microwave quantum communication, since the spatial distribution of vortex microwave quanta of different modes may overlap, this will cause the signals of two or more modes to interfere with each other in the region, making it difficult to perform mode sorting directly. The information recovery unit 403 can, based on mode sorting, first recover the information of the vortex microwave quantum of one mode, and then use this known information to recover the information of the vortex microwave quantum of another mode by means of serial interference cancellation.

[0085] Next, combine Figures 3-5 The information transmission system of vortex microwave quantum proposed in the embodiments of this application will be further described.

[0086] When vortex microwave quanta generated by a transmitter (usually an electron gyroscope) irradiate a non-homogeneous medium interface, reflection, refraction, and scattering occur. Under the influence of the vortex microwave quanta, microscopic particles in the medium gain energy and form vibrating electric dipoles. Scattering is caused by these vibrating electric dipoles becoming secondary wave sources and emitting vortex microwave quanta in all directions. When vortex microwave quanta irradiate a homogeneous medium interface, due to the mutual interference between the secondary waves, only reflection and refraction occur at the medium surface. For the sake of simplicity, the medium is assumed to be an isotropic heterogeneous medium.

[0087] like Figure 3 As shown, for the reflector-lens antenna combination module 200, the vortex microwave quantum source, the reflector antenna (front-mounted), and the spherical lens antenna (rear-mounted) are located at... Figure 3 The transmitter shown in (a) has another reflector antenna located at... Figure 3 (b) shows the receiver end. The vortex microwave quantum source is generated by the high-speed cyclonic motion of electrons produced by the cathode or by a signal source. The vortex microwave quantum emitted from the focal point passes through the reflector antenna (front-mounted) and is incident parallel to the principal axis direction onto the spherical lens antenna (rear-mounted). After passing through the spherical lens antenna, it is further converged and reaches the reflector antenna at the receiver end. To analyze the transmission of the vortex microwave quantum, an x'y'z' coordinate system with O' as the origin is established, S represents the aperture surface of the reflector antenna, which is perpendicular to the transmission direction, and d, f, and θ are... mLet R1, R2, and f represent the diameter, focal length, and half-angle of the reflector antenna, respectively. The curvatures and focal lengths on both sides of the spherical lens antenna are R1, R2, and f, respectively. len The height of the lens antenna from the center to the edge and the refractive index of the material are h, respectively. len and n len The receiver consists of a vortex microwave quantum receiver and a reflective antenna (symmetrical to the transmitter). The vortex microwave quantum particles arrive at the receiver and, after being focused by the reflective surface, fall into the region near the focal point E.

[0088] To uniquely identify the vortex microwave quantum ray tube in the transmission space, a method using initial point combination quaternions is proposed for establishing the model unit of the ray tube. Compared to plane waves, vortex microwave quantum ray tubes also possess the concept of modes, thus requiring an additional dimension to represent the modes and rotation directions. Extending the three-dimensional vector to quaternion form can well represent the spin and modes of the ray tube. In this case, regardless of spatial location, the ray tube can be represented as... At this moment, the incident ray tube S in space i It can be represented as:

[0089]

[0090] When vortex microwave quanta are incident on a microwave dielectric material, the deflection of the reflected and transmitted ray tubes is as follows:

[0091] Δ r =(X r ,Y r Z t );

[0092] Δ t =(X t ,Y t Z t );

[0093] Therefore, the reflecting ray tube and the transmitting ray tube can be represented as follows:

[0094]

[0095] For ray tube path tracing and solving elements, the calculation can be performed as follows.

[0096] exist Figure 4The specific application scenario shown illustrates the case where the vortex microwave quantum has a high refractive index in the medium. In this case, all vortex microwave quantumes (mode 1 and mode 0) emitted from the lens antenna can be covered by the receiving end's reflective surface. Vortex microwave quantum mode 1 lands at point B on the z' axis after passing through the lens antenna, and vortex microwave quantum mode 0 lands at point A on the z' axis after passing through the lens antenna. The distance between points A and B is Δ, the distance between point B and the receiving end's reflective antenna is d2, point C is the intersection of vortex microwave quantum mode 1 and the z' axis after passing through the edge of the reflective antenna, and point D is the intersection of vortex microwave quantum mode 0 and the z' axis after passing through the edge of the reflective antenna. The distance between C and D is δf. mode1 The distance between DE is δf mode0 Assume that the angle between the transmission direction and the principal axis of mode 1 before incident and after passing through the edge of the receiver's reflector antenna is θ'. mode1 and θ mode1 The transmission direction of mode 0 after passing through the edge of the receiver reflector antenna and the angle between the transmission direction and the principal axis are θ' and θ', respectively. mode0 and θ mode0 The vortex microwave quantum receiver is identical to the transmitter, detecting microwave quanta through the coupling of electrons and microwave quanta. The length δf of the vortex microwave quantum in mode 1 falls within the focal length region. mode1 The length δf of the region where the focal length falls for a vortex microwave quantum greater than mode 0. mode0 .

[0097] like Figure 5 This illustrates the case where vortex microwave quanta have a low refractive index in the medium. The vortex microwave quanta emitted from the lens antenna cannot be completely covered by the reflecting surface at the receiver. Vortex microwave quantum mode 1 lands at point B' on the z' axis after passing through the lens antenna, while vortex microwave quantum mode 0 lands at point A' on the z' axis. The distance between points A' and B' is Δ', the distance between point B' and the receiver PA is d′2, and the distance between C' and E' is δf. mode1 The distance between ' and D'E' is δf mode0 Assume that the angle between the transmission direction and the principal axis of mode 1 before incident and after passing through the edge of the receiver PA is θ'. 2-mode1 and θ 2-mode1 The transmission direction of mode 0 after passing the edge of the receiver PA and the angle between the principal axis and the axis are θ', respectively. 2-mode0 and θ 2-mode0 The length δf of the vortex microwave quantum of mode 1 in the region where the focal length falls. mode1 The length δf of the region where the focal length falls for vortex microwave quanta smaller than mode 0. mode0 '.

[0098] Electrons generated at the cathode undergo high-speed gyratory motion within a gyroscope surrounding the magnetic field coil, producing vortex microwave quanta of mode 1. These vortex microwave quanta then exit at the focal point of the reflector antenna after passing through a mode converter and a waveguide. Similarly, plane waves generated by the signal source (vortex microwave quanta of mode 0) also exit at the focal point after passing through the waveguide. The reflector antenna is made of metal, and all vortex microwave quanta of modes 1 and 0 are reflected upon impact with its surface. According to geometric optics and ray tube tracking methods, microwave quanta incident from the focal point to the reflector propagate along parallel principal axes after reflection. Plane wave microwave quanta and vortex microwave quanta are converged by the spherical lens antenna after incident on it. In the case of paraxial incidence, the parameters and focal length of the spherical lens antenna are related as follows:

[0099]

[0100] Since the curvature of the plane is infinite, the radius of one side of the spherical surface of the lens is equal to the curvature. Therefore:

[0101]

[0102] For solving the refractive index and time delay within the medium, when vortex microwave quanta interact with the medium, neglecting the size of the atomic nucleus, it can be approximated as an interaction with free and bound electrons in the medium. In a medium without free electrons, bound electrons orbiting the atomic nucleus release a vortex microwave quantum after absorbing it, resulting in a time delay in the propagation of the vortex microwave quantum. When both free and bound electrons are present in the medium, the free electron portion will resonate under the influence of the incident vortex microwave quantum, simultaneously generating vortex microwave quanta. This portion also introduces a time delay, further reducing the propagation speed of the microwave quantum in the medium. The above process explains why the ray tube composed of vortex microwave quanta slows down and refracts when passing through the medium. The mode value affects the time of absorption and release of quanta by bound electrons, resulting in differences in the refractive index of the medium, ultimately producing a situation different from that of the incident plane wave. In addition, due to the existence of the spin Hall effect, the vortex microwave quantum ray tube reflected by the medium differs from that of a traditional plane wave; the incident and emission positions of the vortex microwave quantum are offset.

[0103] Taking a microwave medium without free electrons as an example, we calculate the refractive index and reflectivity when vortex microwave quanta are incident on the material. Regardless of whether the selection rule is satisfied, the vortex microwave quanta incident on the medium will disturb the bound electrons. After the vortex microwave quanta interact with the bound electrons in the medium, the bound electrons will absorb the vortex microwave quanta on their original trajectory and move away from the atomic nucleus. The position farthest from the atomic nucleus is the intermediate state |m>, and the initial state of the bound electron is |i>. The angular momentum and energy provided by the vortex microwave quanta do not obey the selection rule. When the bound electron reaches the position farthest from the atomic nucleus, it cannot jump to a higher energy level. Therefore, the bound electron will return to its initial trajectory after a time interval τ and re-release the OAM microwave photon, which is recorded as the final state |f>.

[0104] For an OAM microwave photon in free space, its four-dimensional vector potential can be expressed as:

[0105]

[0106] Where k is the wave vector amplitude, η is the polarization, l is the mode of the vortex microwave quantum, p is the radial quantum number, ε is the dielectric constant, z is the position along the principal axis, φ is the spatial azimuth angle, c is the speed of light in vacuum, and A lp Let ω be a constant, hc be the complex conjugate, ω be the angular frequency, and t be time. For the generation and annihilation operators, ε0 is the vacuum permittivity, k is the wave vector, V is the quantization volume, i is the imaginary unit, and h is the reduced Planck constant.

[0107] Among them, f l,p (r) can be represented as:

[0108]

[0109] in, For standardized constants, Let w0 be a p-order generalized Laguerre polynomial, and w0 be a Gaussian waist.

[0110] When vortex microwave quanta are incident on a dielectric material, they interact with the particles in the material, and the matrix element M can be solved further using the perturbation method. m→f :

[0111]

[0112] Among them, H int Let f be the Hamiltonian of the interaction between the vortex microwave quantum and the free electron, |f> be the final state, |m> be the intermediate state, and B be the correction coefficient (generally equal to 1).

[0113] According to Fermi's golden rule, the rate at which bound electrons absorb and emit OAM microwave quanta is:

[0114]

[0115] Where, ρ f Let dΩ be the density of states of an electron after it releases a quantum in the medium, and dΩ be a solid-angle cone.

[0116] Integrating Γ yields Γ m→f The time it takes for a particle in the medium to absorb and re-emit a vortex microwave quantum is:

[0117]

[0118] If the distance that a vortex microwave quantum must travel to encounter an electron in an atom is d, and assuming that the time from the initial state to the intermediate state and from the intermediate state to the final state are approximately the same, what is the average time t that the vortex microwave quantum takes to traverse this distance? m for:

[0119]

[0120] Furthermore, the refractive index can be obtained:

[0121]

[0122] The relationship between refractive index and mode number in vortex microwave quantum media under different media materials is as follows: Figure 6 As shown, the refractive index of the microwave medium gradually decreases and tends to 1 as the absolute value of the mode increases. This phenomenon is because the elements of the transition matrix increase with the increase of the absolute value of the mode, resulting in a larger absolute value of the mode during a shorter computational time for bound electron perturbation, making it more difficult for bound electrons to be disturbed by vortex microwave quanta. Furthermore, when the absolute value of the mode is relatively small, the refractive index is more affected by the mode (the refractive index of mode 3 is about half that of mode 0). As the absolute value of the mode increases, the refractive index is less affected by the mode because the refractive index tends to 1.

[0123] To illustrate the variation of the refractive index of the X-ray tube with the vortex microwave quantum modes within the X-ray tube in the vortex microwave quantum tube analysis method, embodiments of this application selected microwave dielectric ceramic materials and polytetrafluoroethylene (PTFE) materials applicable to the microwave frequency band. These materials typically possess high relative permittivity (10–100), very low dielectric loss, and a temperature coefficient with a resonant frequency close to zero in the microwave frequency band. Table 1 shows some parameters of the 28 GHz microwave dielectric.

[0126] according to Figure 6The relationships between the variations in the focal length and refractive index, the mathematical relationships between the lens focal length and refractive index, and the geometric relationships between the receiving end reflector antenna, as well as the relationships between the lens sorting distance, the reflector sorting distance, and the lens radius of curvature, are respectively expressed as follows: Figure 7 and Figure 8 As shown.

[0127] The serial interference cancellation method will be explained in detail below with reference to specific application scenarios.

[0128] Regarding the serial interference cancellation method used in the signal transmission and computation section, there are mainly two cases: In the first case, after the vortex microwave quanta of mode 0 and mode 1 fall into the DE and CE regions respectively after passing through the reflector at the receiving end, the vortex microwave quantum part of mode 1 in CD can be recovered first. Then, serial interference cancellation is used to eliminate the vortex microwave quantum of mode 1 and realize the recovery of the mode 0 signal. Assume that the intensity distribution of vortex microwave quantum mode 1 in the CD region is E. mode1 (z), the intensity distribution of vortex microwave quantum mode 0 is E mode0 (z) The ambient noise is additive white Gaussian noise n = kTB, where k is the Boltzmann constant, T is Fahrenheit, and B is the transmission data bandwidth.

[0129] For vortex microwave quantum mode 1, the signal-to-interference-plus-noise ratio can be expressed as:

[0130]

[0131] When data is transmitted using modal keying, the average bit error rate obtained from vortex microwave quantum mode 1 measurements is calculated using the Q-function form, i.e.:

[0132]

[0133] In the first case, the process of obtaining a vortex microwave quantum mode with a 0 bit error rate by eliminating serial interference is as follows: Assume that the detection position of vortex microwave quantum mode 1 in segment CD is fixed, and its amplitude is A. mode1 Microwave quantum vortex microwave quantum mode 1 is detected in segment DE, and its amplitude at position z′ is A′. mode1 (z′). The signal S detected at position z′ of the recovered microwave quantum mode 0 in segment DE. DE-mode0 (z′) can utilize the signals S of mode 0 and mode 1. mode0 (z′) and S mode1 (z′) is represented as:

[0134] S dE-mode0 (z′)=S DE-mode0 (z′)+S mode1 (z′)+n;

[0135] The signal S detected at a fixed location in microwave quantum mode 1 of segment CD. CD-mode1 It can be represented as:

[0136]

[0137] Where n and n1 are both additive white Gaussian noise.

[0138] Restore S mode0 (z′):

[0139]

[0140] When using modal keying for transmission, the average bit error rate obtained from microwave quantum mode 0 measurements is calculated using the Q-function form, i.e.:

[0141]

[0142] In the second case, after the vortex microwave quanta of mode 0 and mode 1 fall into regions C'E and D'E respectively after passing through the receiving end reflector, the vortex microwave quantum part of mode 0 in C'E can be recovered first. Then, serial interference cancellation is used to eliminate the vortex microwave quantum of mode 0 and recover the mode 1 signal. Assume that the intensity distribution of vortex microwave quantum mode 0 in region C'D' is E. 2-mode0 (z), the intensity distribution of vortex microwave quantum mode 1 is E 2-mode1 (z).

[0143] For vortex microwave quantum mode 0, the signal-to-interference-plus-noise ratio (SINR) can be expressed as:

[0144]

[0145] When data is transmitted using modal keying, the average bit error rate obtained from vortex microwave quantum mode 0 measurements is calculated using the Q-function form, i.e.:

[0146]

[0147] The calculation of the bit error rate of vortex microwave quantum mode 1 in the second case can refer to the calculation process of the bit error rate of vortex microwave quantum mode 0 in the first case.

[0148] Therefore, by first recovering the information of the vortex microwave quantum in one mode, and then using this known information to eliminate serial interference, the information of the vortex microwave quantum in another mode can be recovered.

[0149] The vortex microwave quantum information transmission system proposed in this application transmits vortex microwave quanta at the feed position through a vortex microwave quantum feed module. A reflective lens antenna combination module enables different modes of vortex microwave quanta to have differentiated transmission paths. An interaction module between the ray tube and the reflective lens antenna models the ray tube and calculates its refractive index by solving for the time delay in the incident medium. An information recovery module performs mode sorting based on the landing regions of different modes of vortex microwave quanta and recovers their information. Thus, by employing a combination of reflective and lens antennas, mode sorting is achieved, and vortex microwave quantum information transmission is completed. This solves the problem of difficult mode sorting at the receiving end in traditional vortex microwave quantum communication transmission, ultimately achieving efficient and accurate information transmission.

[0150] Next, the vortex microwave quantum information transmission method proposed according to the embodiments of this application is described with reference to the accompanying drawings.

[0151] Figure 9 This is a flowchart of a vortex microwave quantum information transmission method according to an embodiment of this application.

[0152] like Figure 9 As shown, this vortex microwave quantum information transmission method employs the following... Figure 1 The vortex microwave quantum information transmission system shown in the embodiment includes the following steps:

[0153] In step S901, the vortex microwave quantum feed module emits vortex microwave quantum signals at the feed position based on a preset mode keying strategy or a preset mode information transmission multiplexing strategy.

[0154] In step S902, the reflective lens antenna combination module is used to perform mode division of the vortex microwave quantum according to the preset geometric relationship and the properties of the vortex microwave quantum, so as to distinguish the vortex microwave quantum of different modes and maximize the difference in the position of the vortex microwave quantum of at least two modes falling into the receiving end region.

[0155] In step S903, the ray tube and the reflector lens antenna interaction module are used to model the ray tube based on the ray tube gain and a preset quaternion strategy to obtain a preset ray tube model. The time delay of the ray tube in the incident medium is solved based on a preset quantum electrodynamic strategy. The refractive index of the ray tube is obtained based on the time delay. The ray tube path through which at least two modes of vortex microwave quantum passes is obtained based on the refractive index.

[0156] In step S904, the information recovery module obtains the landing regions of at least two modes of vortex microwave quanta based on the ray tube path traversed by the vortex microwave quantum. Based on the power measurement strategy and the landing regions, the at least two modes of vortex microwave quantum are sorted by mode. Based on the preset serial interference strategy, the information of the at least two modes of vortex microwave quantum is recovered to obtain the original information.

[0157] It should be noted that the foregoing explanation of the information transmission system embodiment of vortex microwave quantum also applies to the information transmission method of vortex microwave quantum in this embodiment, and will not be repeated here.

[0158] According to the vortex microwave quantum information transmission method proposed in this application, the delay time of the interaction between vortex microwave quanta in the X-ray tube and particles in the medium is solved by employing a preset quantum electrodynamic strategy (i.e., the quantum electrodynamic method) throughout the communication process, thereby obtaining the refractive index and gain of the X-ray tube; simultaneously, a mathematical representation method for the vortex microwave quantum X-ray tube quaternion is established. During vortex microwave quantum transmission, the transmitting end uses a combination of a reflective antenna and a lens antenna to transmit vortex microwave quanta of different modes along different paths, while the receiving end uses a reflective antenna to ensure that vortex microwave quanta of different modes fall into different regions. Finally, vortex microwave quantum mode sorting and information recovery are achieved through power measurement and serial interference cancellation. Therefore, by using a combination of reflective and lens antennas to achieve mode sorting and complete the information transmission of vortex microwave quanta, the problem of difficult mode sorting at the receiving end in traditional vortex microwave quantum communication transmission is solved, ultimately achieving efficient and accurate information transmission.
