Performance gain of displacement receiver with optimized prior probability
M. Fujiwara, S. Izumi, M. Takeoka +1
We numerically study the performance of the displacement based quantum receiver for the discrimination of weak 3- and 4-phase-shift keyed (PSK) coherent state signals. We show that…
Ultrabroadband direct detection of nonclassical photon statistics at telecom wavelength
Kentaro Wakui, Yujiro Eto, Hugo Benichi +7
Broadband light sources play essential roles in diverse fields, such as high-capacity optical communications, optical coherence tomography, optical spectroscopy, and spectrograph c…
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…
