Optimal State Choice for Rydberg-Atom Microwave Sensors
in Physical Review Applied
| Description | Our work has involved a systematic study of the accuracy of atom based microwave field sensors, exposing a number of systematic errors that limit applicability of prior results whilst using a sophisticated model to identify and experimentally verify regimes where atom based sensors offer a truly linear and SI-traceable response. This sensor has been used to perform the analysis of microwave communications using the Rydberg atoms as an antenna with the advantage of being metal free and providing a receiver of smaller size than would be possible using standard antenna designs. Another area of focus has been studying density dependent effects on Rydberg EIT which is important in identifying regimes for calibrated sensing and this will be communicated in a paper in preparation. |
| Exploitation Route | The results of this work provide a route to developing calibrated references for microwave metrology which can be used in a wide range of applications including digital communications and security and defence sectors. This is an active area of research within industry and particularly within aerospace and defence where sensitive detection of RF and microwave signals is important for security and communications applications. |
