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 …

As the quantum information field advances, the need for improved single-photon devices is
becoming more critical. Quantum information systems are often limited by detector deadtime …

We address the problem of how efficiently information can be encoded into and read out
reliably from a passive reflective surface that encodes classical data by modulating the …
