- Differential-phase-shift quantum key distribution experiment using fast physical random bit generator with chaotic semiconductor lasersToshimori Honjo
NTT Basic Research Laboratories, NTT Corporation, 3 1 Morinosato Wakamiya, Atsugi shi, Kanagawa, 243 0198, Japan
Opt Express 17:9053-61. 2009..Stable operation is demonstrated for over one hour, and sifted keys are successfully generated at a rate of 9.0 kbps with a quantum bit error rate of 3.2% after 25-km fiber transmission...
