Experimental quantum key distribution with active phase randomization
Yi Zhao, Bing Qi, Hoi-Kwong Lo
Phase randomization is an important assumption made in many security proofs of practical quantum key distribution (QKD) systems. Here, we present the first experimental demonstrati…

Quantum key distribution with "dual detectors"
Bing Qi, Yi Zhao, Xiongfeng Ma +2
To improve the performance of a quantum key distribution (QKD) system, high speed, low dark count single photon detectors (or low noise homodyne detectors) are required. However, i…
Security of quantum key distribution using weak coherent states with nonrandom phases
Hoi-Kwong Lo, John Preskill
We prove the security of the Bennett-Brassard (BB84) quantum key distribution protocol in the case where the key information is encoded in the relative phase of a coherent-state re…
Security of quantum bit string commitment depends on the information measure
Harry Buhrman, Matthias Christandl, Patrick Hayden +2
Unconditionally secure non-relativistic bit commitment is known to be impossible in both the classical and the quantum world. However, when committing to a string of n bits at once…
Sequential attacks against differential-phase-shift quantum key distribution with weak coherent states
Marcos Curty, Lucy Liuxuan Zhang, Hoi-Kwong Lo +1
We investigate limitations imposed by sequential attacks on the performance of differential-phase-shift quantum key distribution protocols that use pulsed coherent light. In partic…
