A multipixel silicon APD with ultralow dark count rate at liquid nitrogen temperature
M. Akiba, K. Tsujino, K. Sato +1
The dark count rate of a multipixel photon counter (MPPC) was reduced to less than 0.2 cps by cooling the counter to 78.5 K. Characteristics of the MPPC other than the dark count r…

EPR Beams and Photon Number Detector: Toward Synthesizing Optical Nonlinearity
M. Sasaki, K. Wakui, J. Mizuno +2
We present the two kinds of experimental results. One is a continuous variable dense coding experiment, and the other is a photon number detector with high linearity response, the…
