Abstract
In a general aspect, a quantum spectrum sensing system is presented. In some implementations, a system includes a laser system, a vapor cell sensor, an optical detector, and a signal processing system. The laser system includes a first laser that generates a first laser signal; a comb generator that produces a frequency comb signal based on the first laser signal; and a second laser generates a second laser signal. The vapor cell sensor includes a vapor and receives input optical signals based on the frequency comb signal and the second laser signal. The vapor cell sensor produces output optical signals based on interactions of the vapor with the input optical signals and electromagnetic radiation. The signal processing system processes the output optical signals to identifying signals in the electromagnetic radiation that are off resonance with a transition frequency between Rydberg states of the vapor.
