Ultra fast quantum key distribution over a 97 km installed telecom fiber with wavelength-division multiplexing clock synchronization
Akihiro Tanaka, Mikio Fujiwara, Sae Woo Nam +10
We demonstrated ultra fast BB84 quantum key distribution (QKD) transmission at 625 MHz clock rate through a 97 km field-installed fiber using practical clock synchronization based…
Generation of continuous-wave broadband Einstein-Podolsky-Rosen beams using periodically-poled lithium niobate waveguides
Ken-ichiroh Yoshino, Takao Aoki, Akira Furusawa
Continuous-wave light beams with broadband Einstein-Podolsky-Rosen correlation (Einstein-Podolsky-Rosen beams) are created with two independent squeezed vacua generated by two peri…
One-way Quantum Key Distribution System based on Planar Lightwave Circuits
Yoshihiro Nambu, Ken'ichiro Yoshino, Akihisa Tomita
We developed a one-way quantum key distribution (QKD) system based upon a planar lightwave circuit (PLC) interferometer. This interferometer is expected to be free from the backsca…
Experimental demonstration of quantum teleportation of a squeezed state
Nobuyuki Takei, Takao Aoki, Satoshi Koike +8
Quantum teleportation of a squeezed state is demonstrated experimentally. Due to some inevitable losses in experiments, a squeezed vacuum necessarily becomes a mixed state which is…
