| titleOfInvention | Design method of ultra-low noise radio frequency receiver based on Rydberg atomic transition |
| abstract | The invention discloses a design method of an ultra-low noise radio frequency receiver based on Rydberg atomic transition. A Rydberg steam pool is added to the front end of the radio frequency antenna of the traditional receiver, and the particles in the Rydberg steam pool are lasered by laser light. The excitation causes the migration between particles at different energy levels, so that the radio frequency signal is amplified, and then received by the traditional radio frequency antenna into the receiver. In the amplification process, two Rydberg energy levels are included. By using a radio frequency signal to excite the high-level Rydberg atoms, stimulated radiation is generated, and the bound electrons transition from the high-level Rydberg state to the low-level Rydberg state. , releasing a microwave photon with the same frequency, polarization and phase information as the input microwave photon, so that the weak microwave signal can be amplified. The invention is not limited by resistance thermal noise, and overcomes the problem that traditional radio frequency receivers cannot receive power lower than thermal noise. |
