“…Rydberg atoms are also extensively employed in many fields, like high-resolution imaging, millimeter-wave/terahertz [10], and antenna measurement [11]. Owing to the high sensitivity of Rydberg atoms to RF E-field, the concept of wireless communication using Rydberg atoms has been recently proposed and verified.…”

Rydberg atoms have been extensively utilized in microwave measurement with high sensitivity, which has great potential in the field of communication. In this study, we discuss the digital communication based on a Rydberg atomic receiver under simultaneously coupling by resonant and near detuning microwaves. In addition, we verify the feasibility of the Rydberg atom-based frequency division multiplexing (FDM) in microwave communication. We demonstrate the principle and performance of the atom-based FDM receiver by applying amplitude modulation (AM) and frequency modulation (FM), respectively. To demonstrate the actual communication performance at different data transfer rates, we consider monochromatic images as an example. The experimental results show that the maximum acceptable data transfer rate of both AM and FM is about 200 kbps, whereas their maximum bit error rates (BER) is less than 5%. When compared with the traditional electronic receiver, this atomic receiver, which is compatible with FDM, has numerous advantages, such as small size, low power consumption, and high sensitivity. Furthermore, this receiver has a strong ability of anti-electromagnetic interference, and the signals transmitted do not interfere with each other in different channels.

“…On the other hand, in our proposed method, quantum phenomena of atoms are used in lieu of general antenna elements and receivers. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] There are already a few reports of visualization methods using atoms. However, our method is simpler and enables wider and quicker imaging compared to the previous studies.…”

We present a feasibility study of a real-time visualization method for electromagnetic fields. When a resonant laser is used to irradiate gaseous atoms enclosed in a glass cell, the atoms absorb the light and immediately radiate as fluorescence. If a resonant laser and electromagnetic field are used to irradiate the gaseous atoms simultaneously, fluorescence of the light is stronger. The difference between the strength values of fluorescence of light can be used for electromagnetic field visualization. We succeeded in demonstrating a real-time visualization of electromagnetic fields radiated from a horn antenna and an aperture of a waveguide in free space.

“…Based on this conclusion, it remains hard to find an extremely small vapor cell for millimeter-wave or THz field sensing, and using a small vapor cell would also reduce the number of atoms and hence limit the measurement sensitivity. Alternatively, sometimes we can correct such field distortion by numerical simulation, or optimizing a point within a vapor cell volume for laser illumination [ 22 ]. However, this still results in large uncertainty, and the traceability of a numerical simulation is unclear.…”

Highly excited Rydberg atoms in a room-temperature vapor cell are promising for developing a radio-frequency (RF) electric field (E-field) sensor and relevant measurement standards with high accuracy and sensitivity. The all-optical sensing approach is based on electromagnetically-induced transparency and Autler-Townes splitting induced by the RF E-field. Systematic investigation of measurement uncertainty is of great importance for developing a national measurement standard. The presence of a dielectric vapor cell containing alkali atoms changes the magnitude, polarization, and spatial distribution of the incident RF field. In this paper, the field distortion of rubidium vapor cells is investigated, in terms of both field strength distortion and depolarization. Full-wave numerical simulation and analysis are employed to determine general optimization solutions for minimizing such distortion and validated by measuring the E-field vector distribution inside different vapor cells. This work can improve the accuracy of atom-based RF E-field measurements and contributes to the development of related RF quantum sensors.
