This brief introduces a D-band receiver (RX) RF front-end (RFE) integrating a low-noise amplifier (LNA), a mixer, a local oscillation (LO) doubler with pre- and post-buffering stages, and an ...

Abstract: Rydberg-atom quantum receivers (RAQRs) enable ultra-sensitive radio frequency (RF) detection by transducing incident fields into the optical domain with minimal quantum noise. This letter ...
