DETAILED DESCRIPTION

[0022] The utility model is further explained in connection with the drawings and examples.

[0023] Electromagnetic induction transparency is a special nonlinear effect exhibited in the interaction of light and matter, which is a quantum coherence effect produced when two lasers interact with atoms. For Rydberg atoms, electromagnetic induction transparency phenomenon will also be exhibited under certain conditions, i.e. Rydberg atom electromagnetic induction transparency effect.

[0024] Principle

[0025] Rydberg atom refers to a highly excited state atom with a large principal quantum number, which has the characteristics of large radius, large electric dipole moment, long lifetime, and strong interaction. When a control light and a probe light act on a Rydberg atom, if the frequency difference between the control light and the probe light and the related energy level of the Rydberg atom satisfies the specific resonance condition, electromagnetic induction transparency effect will be produced. Specifically, the control light causes the coherent superposition between the two energy levels of the atom, thereby changing the absorption characteristics of the atom to the probe light, so that the probe light can pass through the atomic medium almost without absorption at the frequency that should be strongly absorbed, showing a transparent effect.

[0026] Characteristics

[0027] High sensitivity: Rydberg atoms are extremely sensitive to external electromagnetic fields, which enables devices based on Rydberg atom electromagnetic induction transparency effect to respond significantly to weak electromagnetic field changes, thereby achieving high sensitivity detection. For example, a miniaturized high-sensitivity short-wave atomic antenna developed by the University of Defense Science and Technology can receive long-distance civilian broadcast signals.

[0028] Slow light effect: In the process of electromagnetically induced transparency, the group velocity of probe light can be significantly reduced, even to a few meters per second or even lower. This slow light effect provides the possibility for optical signal storage, processing and manipulation, such as realizing optical pulse delay, storage and prolonging the interaction time between light and matter.

[0029] Strong nonlinear effect: The strong dipole-dipole interaction between Rydberg atoms leads to strong nonlocal optical Kerr effect and other nonlinear effects. By utilizing these nonlinear effects, special optical phenomena such as stable high-dimensional optical soliton molecules can be realized in ultracold Rydberg atomic gases, providing new ideas and methods for optical information processing and other fields.

[0030] Applications

[0031] Quantum information processing: It can be used to prepare single photon source, realize quantum storage and reading, etc., and provide key technical support for quantum communication and quantum computing and other quantum information fields. For example, by controlling the electromagnetically induced transparency effect of Rydberg atoms, on-demand generation and efficient storage of photons can be realized, thereby constructing reliable quantum storage units.

[0032] Microwave detection: Due to the sensitivity of Rydberg atoms to microwave electric field and the enhancement effect brought by electromagnetically induced transparency, it can be used to manufacture high-sensitivity and high-resolution microwave sensors for microwave signal detection and measurement in radar, communication and other fields.

[0033] Generation and manipulation of optical soliton molecules: By utilizing the electromagnetically induced transparency effect and strong nonlocal optical Kerr effect of Rydberg atoms, stable high-dimensional weak optical soliton molecules can be generated and actively manipulated, which is expected to become a new type of information carrier and be applied in optical information processing and transmission.

[0034] Rydberg atom electromagnetically induced transparency angle measurement device is mainly used for high-precision measurement of angle and realization of precise measurement of microwave electric field and other physical quantities.

[0035] High-precision angle measurement: By utilizing the special properties of Rydberg atoms and electromagnetically induced transparency effect, the device can realize high-precision measurement of angle, which has important application value in many fields requiring accurate angle information, such as optics, precision machinery, aerospace, etc.

[0036] Precise measurement of microwave electric field: Rydberg atoms are very sensitive to microwave electric field. By measuring the change of electromagnetically induced transparency effect of Rydberg atoms under the action of microwave electric field, the strength, direction and other parameters of microwave electric field can be indirectly measured.

[0037] The Rydberg atom electromagnetic induction transparent effect angle measuring device has the advantages of high precision, high sensitivity, etc., and provides a new means for precise measurement of microwave electric field. However, the Rydberg atom electromagnetic induction transparent effect angle measuring device usually has some problems in actual use, some common problems and their causes are listed as follows: 1. Limited measurement precision: the main reason may be that the sensitivity of Rydberg atom to the environment may cause it to be disturbed by external magnetic field, electric field or temperature during the experiment, thereby affecting the measurement precision; the precision, stability of experimental equipment and errors in operation process may also affect the measurement precision.

[0038] 2. Signal interference and identification difficulty: the main reason may be that multiple frequency microwaves can cause complex interference modes in atoms, which can seriously interfere with signal reception and identification, especially when multiple frequency microwave measurement is performed; electromagnetic noise, mutual interference between devices and imperfect signal processing algorithm can also cause signal identification difficulty. 3. Difficulty in controlling experimental conditions: the main reason may be that the experimental conditions of Rydberg atom electromagnetic induction transparent effect are relatively harsh, such as the need for specific atomic density, temperature and laser parameters, and small changes in these conditions can affect the experimental results; the cleanliness of experimental environment, electromagnetic shielding effect and operation level of experimental personnel can also affect the experimental conditions.

[0039] 4. Device complexity and cost: the main reason may be that in order to achieve high precision angle measurement, the Rydberg atom electromagnetic induction transparent effect angle measuring device usually needs complex laser system, precise detector and data processing equipment, which increases the complexity and cost of the device; maintenance, calibration and upgrading of the device also need professional technical support and high cost investment.

[0040] There are various types of Rydberg atom electromagnetically induced transparency effect angle measurement devices on the market, aiming to achieve high-precision angle measurement and explore and utilize the unique physical properties of Rydberg atoms. In the following, several common Rydberg atom electromagnetically induced transparency effect angle measurement devices will be introduced in detail: 1. Angle measurement device based on double atomic vapor bubble interference: composed of two different wavelength lasers, two identical atomic vapor bubbles, two identical photodetectors, and corresponding optical elements such as beam splitters, dichroic mirrors, and mirrors. Working principle: the laser emitted by the first laser is divided into two identical sub-beams, which are reflected to a photodetector after passing through two atomic vapor bubbles; the laser emitted by the second laser is also divided into two identical sub-beams, which are incident into an atomic vapor bubble respectively. The positions of the two atomic vapor bubbles are mirror-symmetric. When the two sub-beams are incident into the atomic vapor bubble, the alkali metal atoms in the atomic vapor bubble transition to the Rydberg state to become Rydberg atoms and produce electromagnetically induced transparency effect. When there is an incident electromagnetic wave, the transmission peak produced by the electromagnetically induced transparency effect will produce Autler-Townes splitting. By measuring the splitting of the transmission peak received by the two photodetectors and combining relevant optical and electromagnetic principles, the incident angle of the electromagnetic wave can be calculated, and angle measurement can be realized. 2. Angle measurement device based on Rydberg atom mixing: mainly includes Rydberg atom cell, laser system for generating and controlling laser, mixer capable of realizing signal mixing, and related circuit and equipment for signal detection and processing. Working principle: electromagnetically induced transparency effect is produced by the interaction between atoms in the Rydberg atom cell and laser. Two lasers generated by the laser system act on the Rydberg atom, making it in a specific quantum state. When the incident radio frequency signal interacts with the Rydberg atom, it will change the state of the atom, and then affect the propagation and interaction of the laser in the atom. The laser signal after the atom interaction is mixed with the reference signal by the mixer to obtain the intermediate frequency signal containing angle information. Finally, the intermediate frequency signal is analyzed and processed by the signal detection and processing equipment to extract the angle information, thereby realizing the measurement of the angle of the radio frequency signal.

[0041] Although there are various types of Rydberg atom electromagnetically induced transparency effect angle measurement devices on the market, there are still some problems and challenges, such as the Rydberg atom electromagnetically induced transparency effect angle measurement devices mentioned above, each has its own problems: 1. Angle measurement device based on double atomic vapor bubble interference: complex device, high cost, strict environmental requirements, limited measurement range, and complex data processing. 2. Angle measurement device based on Rydberg atom mixing: low mixing efficiency, high laser frequency stability requirement, difficult quantum state manipulation, and large system complexity and volume.
