Time-shift attack in practical quantum cryptosystems
Bing Qi, Chi-Hang Fred Fung, Hoi-Kwong Lo +1
Recently, a new type of attack, which exploits the efficiency mismatch of two single photon detectors (SPD) in a quantum key distribution (QKD) system, has been proposed. In this p…

Experimental Quantum Key Distribution with Decoy States
Yi Zhao, Bing Qi, Xiongfeng Ma +2
To increase dramatically the distance and the secure key generation rate of quantum key distribution (QKD), the idea of quantum decoys--signals of different intensities--has recent…

Practical Decoy State for Quantum Key Distribution
X. Ma, B. Qi, Y. Zhao +1
Decoy states have recently been proposed as a useful method for substantially improving the performance of quantum key distribution. Here, we present a general theory of the decoy…
