Experimental Determination of the Gain Distribution of an Avalanche Photodiode at Low Gains
Kenji Tsujino, Makoto Akiba, Masahide Sasaki
A measurement system for determining the gain distributions of avalanche photodiodes (APDs) in a low gain range is presented. The system is based on an ultralow-noise charge--sensi…
7 dB quadrature squeezing at 860 nm with periodically-poled KTiOPO4
Shigenari Suzuki, Hidehiro Yonezawa, Fumihiko Kannari +2
We observed -7.2 dB quadrature squeezing at 860 nm by using a sub-threshold continuous-wave pumped optical parametric oscillator with a periodically-poled KTiOPO4 crystal as a nonl…
Theory of multiwave mixing and decoherence control in qubit array system
M. Sasaki, A. Hasegawa, J. I. Hayase +2
We develop a theory to analyze the decoherence effect in a charged qubit array system with photon echo signals in the multiwave mixing configuration. We present how the decoherence…
