The Quantum Rydberg RF Sensor is an optoelectronic platform developed by Gradiant that uses Rydberg atoms to detect radiofrequency (RF) signals through optical techniques. Its operation is based on electromagnetically induced transparency (EIT), a phenomenon that makes it possible to observe the response of the atomic system to target RF signals
The amplitude of these signals is reflected in the optical spectrum of the atoms, providing a means of measuring and analysing them. The solution combines quantum technologies, optics and radiofrequency to explore new sensing capabilities, with potential applications in signal characterisation and the development of advanced electromagnetic environment monitoring systems.
Quantum Rydberg RF Sensor detects target RF signals and enables their amplitude to be measured using the optical response of an atomic system. This capability allows radiofrequency signals to be studied using a platform that combines quantum sensing and optical readout. It can be used for experimental characterisation and the development of new spectrum monitoring tools. In fields such as telecommunications and aerospace, this approach provides a technological foundation for exploring new ways to observe the radiofrequency environment.
This sensor enables the amplitude information of an RF signal to be transferred to the optical domain, where it can be observed and analysed through the response of the atoms. Its value lies in bridgingn the capabilities of quantum sensing with radiofrequency measurements requirements, opening up new possibilities for the development of advanced instrumentation. For research and development teams, this platform provides a foundation for exploring detection methods, assesing their suitability for specific applications and advancing towards solutions that combine quantum, photonic and electronic technologies.
