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…

Displacement receiver for phase-shift-keyed coherent states
Shuro Izumi, Masahiro Takeoka, Mikio Fujiwara +4
Quantum receiver is an important tool for overcoming the standard quantum limit (SQL) of discrimination errors in optical communication. We theoretically study the quantum receiver…

Transient differential reflectivity of ferromagnetic and paramagnetic phases in the bilayered manganite La1.24Sr1.76Mn2O7
Y. Hirobe, Y. Kubo, K. Kouyama +3
Photoinduced effects in a single crystal of bilayered manganites, La2-2xSr1+2xMn2O7 (x=0.38), were investigated in a wide range of temperatures by pump-probe measurement at a photo…
