Antinormally Ordered Photodetection of Continuous-mode Field
Koji Usami, Akihisa Tomita, Kazuo Nakamura
When the electromagnetic field is detected by stimulated emission, rather than by absorption, antinormally ordered photodetection can be realized. One of the distinct features of t…

Single-photon interference experiment over 100 km for quantum cryptography system using a balanced gated-mode photon detector
Hideo Kosaka, Akihisa Tomita, Yoshihiro Nambu +2
We demonstrate single-photon interference over 100 km using a balanced gated-mode photon detector and a plug & play system for quantum key distribution. The visibility with 0.1 pho…
