Record Photon Information Efficiency with Optical Clock Transmission and Recovery of 12.5 bits/photon After 77 dB of Optical Path Loss

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