Microwave signals in the frequency range of 1-10 GHz are natural information carriers in many well-known classical applications such as radar, mobile communication, or information processing. Consequently, microwave quantum communication & sensing is set to play an important role in future quantum networks and sensing systems because of its natural compatibility with the frequencies of superconducting quantum processors and modern communication standards. Various applications of propagating quantum microwaves include quantum radar schemes, distributed superconducting quantum computing approaches, and free-space microwave quantum cryptography protocols compatible with 5G/6G architectures.

In particular, our research focuses on the continuous-variable regime, which offers various advantages in terms of robustness and technology for generation & control of squeezed microwave states. Since today’s road to quantum information processing is typically based on the digital approach, we also put a special emphasis on investigating hybrid interactions between discrete- and continuous-variable quantum circuits and signals.
