A Rydberg-atom receiver of QAM signals

Our warm Rydberg atom-based quadrature amplitude-modulated receiver is published in Optics Express 32, 30027.

The receiver works near the 2.4 GHz Wi-Fi band and decodes quadrature-amplitude-modulated data with heterodyne detection, with a sensitivity of 0.50 µV cm⁻¹ Hz⁻¹ᐟ².
