Quantum receivers with squeezing and photon-number-resolving detectors

Shuro Izumi, Masahiro Takeoka, Kazuhiro Ema +1

We propose quantum receivers with optical squeezing and photon-number-resolving detector (PNRD) for the near-optimal discrimination of quaternary phase-shift-keyed coherent state s…
