Portable Quantum Spectrum Sensing Systems

Abstract

In a general aspect, a portable quantum spectrum sensing system for detecting electromagnetic radiation in an environment is presented. In some implementations, a portable system includes a vapor cell sensor and a portable control package. The vapor cell sensor includes a vapor and is configured to generate output optical signals based on interactions between input optical signals, the vapor and the electromagnetic radiation. The portable control package includes a laser system configured to generate laser signals and a photonic integrated circuit system configured to generate the input optical signals based on the laser signals from the laser system. The portable control package includes a system-on-chip that can communicate control signals to the laser system and the photonic integrated circuit system. The system-on-chip can also process the output optical signals to determine one or more properties of the electromagnetic radiation.
