DPS quantum key distribution and related technologies

DPS quantum key distribution and related technologies A unique quantum key distribution (QKD) protocol, called DPS (differential-phase-shift) QKD, has been proposed and developed at NTT and Osaka University, which utilizes a coherent pulse train instead of individual photons as in traditional QKD protocols such as BB84. Its security is based on the fact that every phase difference of a highlyattenuated coherent pulse train cannot be fully measured. This protocol has features of simple setup, potential for a high key creation rate, and robustness against photon-number-splitting attack. This paper presents recent research activities on DPS-QKD. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Proceedings of SPIE SPIE

Abstract

A unique quantum key distribution (QKD) protocol, called DPS (differential-phase-shift) QKD, has been proposed and developed at NTT and Osaka University, which utilizes a coherent pulse train instead of individual photons as in traditional QKD protocols such as BB84. Its security is based on the fact that every phase difference of a highlyattenuated coherent pulse train cannot be fully measured. This protocol has features of simple setup, potential for a high key creation rate, and robustness against photon-number-splitting attack. This paper presents recent research activities on DPS-QKD.
