[0022] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0023] The present invention provides a coordinate migration method and device using quantum entanglement, which will be described separately below.

[0024] Figure 3 FIG. is a schematic flowchart of an embodiment of the coordinate migration method using quantum entanglement provided by the present invention. As Figure 3 shown, the coordinate migration method using quantum entanglement includes: S301. Obtain a pair of entangled particles; the pair of particles includes a first particle located at a reference position and a second particle located at a target position; S302. Obtain the spatial coordinates of the space to be migrated at the reference position and encode the spatial coordinates to be migrated into the quantum state of the first particle; S303. Measure the quantum state of the second particle and decode the quantum state of the second particle to obtain the migrated spatial coordinates in the same spatial coordinate system as the spatial coordinates to be migrated.

[0025] Among them, the method for obtaining the pair of particles in step S301 is: generating a pair of entangled particles in real time based on a quantum device. Among them, the quantum device is any one of a photon source and a superconducting qubit device.

[0026] Among them, an entangled state describes a special relationship existing between two or more quantum particles, such that their states are correlated regardless of the distance between them. Specifically, if the state of one particle changes, then the state of the particle entangled with it will also change immediately, and this state is not affected by distance.

[0027] In a specific embodiment of the present invention, the measurement of the quantum state of the second particle in step S303 is specifically: measuring the quantum state of the second particle using the Bell state measurement method. The Bell state measurement can recover stable information in a variety of noisy environments and does not depend on external factors such as environmental optical fibers and temperature, ensuring the measurement accuracy and reliability.

[0028] Specifically, the measurement parameters of the quantum state can be parameters such as the phase difference and amplitude difference of the quantum state.

[0029] Compared with the prior art, the coordinate migration method using quantum entanglement provided by the embodiments of the present invention obtains the migration space coordinates of the target position based on particles in an entangled state, realizes the same coordinate system for the target position and the migration position, and uses the non-locality and high stability of the quantum entangled state to solve the technical problems such as signal dependence, error accumulation, and environmental limitations existing in the traditional coordinate migration method by encoding the coordinates of the space to be migrated onto the quantum entangled state and performing lossless transmission, improving the accuracy of coordinate migration.

[0030] Furthermore, the embodiments of the present invention utilize the instantaneity and real-time nature of quantum state transmission, enabling the target position to immediately receive and decode the coordinate information, achieving real-time response, improving the determination speed of coordinate migration, and ensuring the synchronization of coordinate information even in high-dynamic scenarios (such as moving drones, robots, etc.), avoiding the common delay problems in traditional positioning methods and meeting the positioning requirements for rapid response.

[0031] To reduce the loss of the second particle during the transmission to the target position, in some embodiments of the present invention, the obtaining of the pair of particles in an entangled state in step S301 includes: Generating an initial pair of particles in an entangled state based on a quantum device; the initial pair of particles includes a first particle and a second particle; Transmitting the first particle to a reference position based on a particle transmission medium, and transmitting the second particle to the target position.

[0032] Among them, the particle transmission medium can be a stable low-loss medium. In a specific embodiment of the present invention, the particle transmission medium is an optical fiber.

[0033] By using a low-loss medium, only the loss of the second particle during transmission can be reduced. However, since the loss of the second particle during transmission cannot be completely avoided, to ensure the accuracy of coordinate migration, in some embodiments of the present invention, such asFigure 4 As shown, before step S302, the coordinate migration method using quantum entanglement further includes: S401. Determine the existence duration of the particle pair, and determine whether the existence duration is greater than a preset duration; S402. When the existence duration is greater than the preset duration, regenerate an updated particle pair, and perform coordinate migration based on the updated particle pair.

[0034] Since the loss degree is proportional to the existence duration of the particle pair to a certain extent, therefore, in the embodiment of the present invention, by setting that when the existence duration of the particle pair is greater than the preset duration, an updated particle pair is regenerated, and coordinate migration is performed based on the updated particle pair. By dynamically generating and updating the entangled pair, the quantum entanglement stability during long-term operation is ensured, and the influence of the decay of the entangled state is avoided. In other words, it is ensured that the coordinate migration system can always maintain the stability of quantum entanglement during long-term and continuous positioning processes, thereby ensuring the persistence and reliability of coordinate migration. In a continuously changing environment, the entangled pair can be automatically adjusted and replaced to ensure the continuous and efficient operation of the system.

[0035] It should be noted that when the existence duration is less than or equal to the preset duration, the quantum state of the second particle is directly measured.

[0036] It should be understood that: the preset duration can be set according to actual application scenarios and requirements, and no specific limitation is made here.

[0037] It should be noted that: the preset duration can be determined based on establishing a quantum key negotiation mechanism between the reference point position and the target position.

[0038] In the embodiment of the present invention, by setting the preset duration to be determined based on the quantum key negotiation mechanism, the update process can be automatically implemented, seamless switching can be achieved, and continuous coordinate migration can be ensured.

[0039] In a specific embodiment of the present invention, the quantum coding algorithm for encoding the spatial coordinates to be migrated into the quantum state of the first particle is any one of a phase coding algorithm, an amplitude coding algorithm, and a phase-amplitude combined coding method.

[0040] In the embodiment of the present invention, by setting multiple quantum coding algorithms, the diversity of the method for encoding the spatial coordinates to be migrated into the quantum state of the first particle is improved.

[0041] In a specific embodiment of the present invention, if the spatial coordinates to be migrated include an X-axis coordinate value, a Y-axis coordinate value, and a Z-axis coordinate value, then when the quantum coding algorithm is a phase-amplitude combined coding algorithm, encoding the spatial coordinates to be migrated into the quantum state of the first particle in step S302 includes: Encode the X-axis coordinate value as the phase of the first particle, encode the Y-axis coordinate value as the amplitude of the first particle, and encode the Z-axis coordinate value as the relative phase difference of the first particle.

[0042] It should be noted that: in the process of encoding the X-axis coordinate value as the phase of the first particle, encoding the Y-axis coordinate value as the amplitude of the first particle, and encoding the Z-axis coordinate value as the relative phase difference of the first particle, the encoding can be achieved through the Bell state generation method, mapping the coordinate information to a specific quantum state to ensure that the target position can be decoded without loss.

[0043] Since the quantum states of the particles in the particle pair are sensitive to the noise and interference of the external environment, they are prone to errors during the transmission process. To correct the quantum states even when errors occur and further ensure the reliability of coordinate migration, in some embodiments of the present invention, after step S302, the method for coordinate migration using quantum entanglement further includes: Encoding the quantum state of the first particle into a quantum error correction code composed of multiple qubits based on the quantum error correction coding mechanism; The quantum state of the second particle is a logical quantum state composed of multiple qubits. Then, the decoding of the quantum state of the second particle in step S303 includes: Correcting the logical quantum state based on the quantum error correction mechanism corresponding to the quantum error correction code to obtain a corrected quantum state, and decoding the corrected quantum state.

[0044] In a specific embodiment of the present invention, the quantum error correction code can be the Shor's code, which encodes 9 qubits into a logical qubit. When any error occurs in a certain qubit, the correct qubit can still be determined based on the quantum error correction mechanism.

[0045] It should be noted that: the quantum error correction code can also be the Steane code, the surface code, etc., which will not be elaborated one by one here.

[0046] In the embodiment of the present invention, by implanting the quantum error correction code into the first particle, it is ensured that even if there are small errors during the transmission process, self-correction can be performed. During the decoding process at the target position, the measurement data is corrected through the quantum error correction mechanism to ensure that the finally obtained coordinate information has high accuracy. This process is applicable to situations where the external environment is unstable or the transmission path is complex, and can significantly reduce error accumulation.

[0047] Since the geophysics and other fields need to obtain the spatial coordinates jointly composed of the X, Y, and Z dimensions, to further improve the efficiency and synchronization of coordinate migration, in some embodiments of the present invention, obtaining the particle pair in an entangled state in step S301 includes: Determine the dimension of the spatial coordinates to be migrated, and determine the number of particle pairs based on the dimension; each particle pair is used to perform coordinate migration on the spatial coordinates to be migrated in one dimension.

[0048] In the embodiments of the present invention, by setting the number of particle pairs equal to the number of dimensions of the spatial coordinates to be migrated, the purpose of separately encoding and transmitting the coordinate information of different dimensions can be achieved through multiple particle pairs. Multidimensional encoding and parallel transmission improve the efficiency of coordinate migration, avoid the bandwidth limitation of single entangled state transmission, and enable coordinate migration to adapt to more complex spatial position requirements. The parallel measurement of multi-dimensional information further ensures the high precision of coordinate synchronization and is applicable to multi-dimensional positioning in complex environments.

[0049] In a specific embodiment of the present invention, when the spatial coordinates to be migrated include three dimensions of X, Y, and Z, three particle pairs in an entangled state are obtained, and the three particle pairs are respectively used to encode and transmit the X-axis coordinates, Y-axis coordinates, and Z-axis coordinates.

[0050] To ensure the information security of the spatial coordinates to be migrated during the transmission process, in some embodiments of the present invention, encoding the spatial coordinates to be migrated into the quantum state of the first particle in step S302 further includes: Encrypt the spatial coordinates to be migrated through the quantum key distribution (QKD) technology to obtain the encrypted spatial coordinates to be migrated, and encode the encrypted spatial coordinates to be migrated into the quantum state of the first particle.

[0051] Among them, quantum key distribution uses the characteristics of quantum mechanics to ensure communication security. Enable both parties of the communication to generate and share a random and secure key to encrypt and decrypt messages.

[0052] In the embodiments of the present invention, the spatial coordinates to be migrated are encrypted through the quantum key distribution technology, so that external interference cannot steal or tamper with the coordinate information, which is applicable to high-security scenarios. Even in the case of malicious interference or eavesdropping, the confidentiality and integrity of the coordinate information can be ensured, greatly improving the security of the coordinate migration technology.

[0053] As can be seen from the foregoing description: the quantum state is affected by the environment. Therefore, to further ensure the accuracy of the migrated spatial coordinates, in some embodiments of the present invention, as Figure 5 shown, the coordinate migration method using quantum entanglement further includes: S501. Obtain multiple preset calibration coordinates of multiple target positions; S502. Perform multiple coordinate migrations based on the particle pairs to obtain multiple migrated spatial coordinates, and determine multiple coordinate differences between the multiple migrated spatial coordinates and the multiple preset calibration coordinates; S503. Determine the average value of the differences of the multiple coordinate differences, and correct the migrated spatial coordinates based on the average value of the differences.

[0054] Among them, the preset calibration coordinates are the coordinates of the target position determined based on a traditional algorithm and verified by experts.

[0055] The multiple coordinate migrations based on particle pairs in step S501 refer to transmitting the second particle to multiple target positions with different spatial positions, measuring each target position, and determining the migration spatial coordinates of each spatial position based on the measurement results.

[0056] In the embodiment of the present invention, by correcting the migration spatial coordinates based on multiple preset calibration coordinates and multiple coordinate differences, the accuracy of the finally obtained migration spatial coordinates can be ensured, and the positioning accuracy can be further improved.

[0057] In summary, the coordinate migration method using quantum entanglement proposed in the embodiments of the present invention has the following advantages: First, by utilizing the non-locality of the quantum entanglement state, that is, the state correlation between entangled particle pairs is not restricted by distance and can instantaneously transmit information. By leveraging the non-locality of quantum entanglement, the present invention does not need to rely on traditional signal transmission methods and can achieve coordinate migration in deep sea, underground, or signal-blocked environments, overcoming the limitations of signal dependence and enabling the coordinate migration system to achieve high-precision positioning in extreme environments. Second, the coordinate information is directly encoded into the quantum state, and information is transmitted through the entangled state, avoiding the interference and attenuation easily suffered during traditional signal transmission. The encoding and transmission of the quantum state are not affected by traditional electromagnetic interference and can maintain the integrity and losslessness of the coordinate information. During the transmission process, the accuracy will not decrease due to signal attenuation, making it suitable for high-interference environments and improving the stability and accuracy of coordinate migration. Third, in the process of quantum encoding and transmission of coordinate information, quantum error correction codes are added to ensure the accuracy of the transmitted information. The quantum error correction mechanism can effectively correct the quantum state deviation caused by environmental factors or measurement errors, ensuring that the decoded coordinate information is highly accurate. This technology ensures that even during long-term transmission, the error of coordinate migration can be effectively controlled, eliminating the problem of error accumulation in traditional methods such as inertial navigation. Fourth, by utilizing the instantaneity and real-time nature of quantum state transmission, the target position can instantaneously receive and decode the coordinate information. The coordinate migration system can achieve real-time response, and even in high-dynamic scenarios (such as moving drones, robots, etc.), it can ensure the synchronization of coordinate information, avoiding the common delay problems in traditional positioning methods and meeting the positioning requirements for rapid response. Fifth, by generating multiple pairs of entangled particle pairs, the coordinate information in different dimensions is separately encoded and transmitted in parallel, which is suitable for coordinate migration in three-dimensional space or even higher-dimensional spaces. Multidimensional encoding and parallel transmission improve the efficiency of coordinate migration, avoiding the bandwidth limitation of single-entangled state transmission, enabling the system to adapt to more complex spatial position requirements. The parallel measurement of multi-dimensional information further ensures the high accuracy of coordinate synchronization and is suitable for multi-dimensional positioning in complex environments. Sixth, by dynamically generating and updating entangled pairs, the stability of quantum entanglement during long-term operation is ensured, avoiding the influence of the attenuation of the entangled state. This mechanism ensures that the coordinate migration system can always maintain the stability of quantum entanglement during long-term and continuous positioning processes, thereby ensuring the persistence and reliability of coordinate migration. In a continuously changing environment, it can automatically adjust and replace entangled pairs to ensure the continuous and efficient operation of the system. Seventh, the coordinate information is encrypted through quantum key distribution technology to ensure the information security during transmission. This encryption mechanism makes it impossible for external interference to steal or tamper with the coordinate information, making it suitable for high-security scenarios. Even in the case of malicious interference or eavesdropping, the system can ensure the confidentiality and integrity of the coordinate information, greatly improving the security of the coordinate migration technology.

[0058] In summary, through these key technical means, the embodiments of the present invention significantly improve the stability, accuracy, and security of coordinate migration, enabling coordinate migration to maintain high precision and high stability even in extreme environments, and having broad application prospects.
