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…
Megabits secure key rate quantum key distribution
Q. Zhang, H. Takesue, T. Honjo +10
Quantum cryptography (QC) can provide unconditional secure communication between two authorized parties based on the basic principles of quantum mechanics. However, imperfect pract…
Hong-Ou-Mandel dip using photon pairs from a PPLN waveguide
Qiang Zhang, Hiroki Takesue, Carsten Langrock +3
We experimentally observed a Hong-Ou-Mandle dip with photon pairs generated in a periodically poled reverse-proton-exchange lithium niobate waveguide with an integrated mode demult…
Entanglement generation using silicon wire waveguide
Hiroki Takesue, Yasuhiro Tokura, Hiroshi Fukuda +4
We report the first entanglement generation experiment that utilizes a silicon waveguide. Using spontaneous four-wave mixing in a 1.09-cm-long silicon wire waveguide, we generated…
Quantum secret sharing based on modulated high-dimensional time-bin entanglement
Hiroki Takesue, Kyo Inoue
We propose a new scheme for quantum secret sharing (QSS) that uses a modulated high-dimensional time-bin entanglement. By modulating the relative phase randomly by {0,pi}, a sender…
