Abstract

The electromagnetic spectrum is limited. As demand increases, our capabilities will be dictated by the sensitivity and agility of RF transmitters, receivers, and networks. For this reason, quantum RF sensors and networks are the key to controlling the spectrum in the tomorrow's competitive landscape. Here, we present a Rydberg-atom based quantum spectrum analyzer that operates continuously from zero to 20 GHz, with sensitivity and instantaneous bandwidth that rivals high-end conventional spectrum analyzers. The spectrum analyzer uses room-temperature Rydberg atoms coupled to an RF waveguide, and input signals are amplified using an off-resonant atomic heterodyne technique. We measure weak ambient signals inside the laboratory including AM/FM radio, Wi-Fi, and Bluetooth. The quantum spectrum analyzer is characterized by unique capabilities that will allow it, in the near future, to surpass foundational limitations of traditional RF receivers and analyzers.
