Atom-based receiver for amplitude-modulated baseband signals in high-frequency radio communication
Atom-based receiver for amplitude-modulated baseband signals in high-frequency radio communication
An optical probe of cesium Rydberg atoms generated in a thermal vapor cell is used to retrieve a baseband signal modulated onto a 16.98-GHz carrier wave in real-time, demonstrating an atom-based quantum receiver suitable for microwave communication. The 60$S_{1/2}$ Rydberg level of cesium atoms in the cell is tracked via …
