Abstract
In a general aspect, a method is described herein for detecting the phase properties of a radio frequency (RF) wave. The method includes generating an optical signal by interacting laser signals with a vapor of a vapor cell sensor. The optical signal is based on a transmission of one of the laser signals through the vapor. The method also includes altering an intensity of the optical signal by interacting a target RF electromagnetic field with a Rydberg electronic transition of the vapor. The target RF electromagnetic field includes a time series of RF pulses. The method additionally includes determining, by operation of a signal processing system, a magnitude of phase change in the time series of RF pulses. In some implementations, the method includes determining a phase of a target RF pulse in the times series of RF pulses.
