Coexistence of Continuous Variable Quantum Key Distribution and 7 12.5 Gbit/s Classical Channels
Tobias A. Eriksson, Takuya Hirano, Motoharu Ono +6
We study coexistence of CV-QKD and 7 classical 12.5 Gbit/s on-off keying channels in WDM transmission over the C-band. We demonstrate key generation with a distilled secret key rat…
Quantum key distribution with an efficient countermeasure against correlated intensity fluctuations in optical pulses
Ken-ichiro Yoshino, Mikio Fujiwara, Kensuke Nakata +7
Quantum key distribution (QKD) allows two distant parties to share secret keys with the proven security even in the presence of an eavesdropper with unbounded computational power.…
Time-bin entangled photon pair generation from Si micro-ring resonator
Ryota Wakabayashi, Mikio Fujiwara, Ken-ichiro Yoshino +3
We demonstrate time-bin entanglement generation in telecom wavelength using a 7 μm radius Si micro-ring resonator pumped by a continuous wave laser. The resonator structure can enh…
Modified E91 protocol demonstration with hybrid entanglement photon source
Mikio Fujiwara, Ken-ichiro Yoshino, Yoshihiro Nambu +7
We report on an experimental demonstration of the modified Ekert 91 protocol of quantum key distribution using a hybrid entanglement source with two different degrees of freedoms,…
Maintenance-free Operation of WDM Quantum Key Distribution System through a Field Fiber over 30 Days
Ken-ichiro Yoshino, Takao Ochi, Mikio Fujiwara +2
Maintenance-free wavelength-division-multiplexing quantum key distribution for 30 days was achieved through a 22-km field fiber. Using polarization-independent interferometers and…
Field test of quantum key distribution in the Tokyo QKD Network
M. Sasaki, M. Fujiwara, H. Ishizuka +40
A novel secure communication network with quantum key distribution in a metropolitan area is reported. Different QKD schemes are integrated to demonstrate secure TV conferencing ov…
