Abstract

We experimentally demonstrate optical detection at 12.5 bits per incident photon, 9.4 dB higher than the theoretical limit of conventional coherent detection. A single laser transmits both data and optical clock, undergoes 77 dB of attenuation before quantum detection followed by optical clock and data recovery.
