Quantum key distribution with an unknown and untrusted source
Yi Zhao, Bing Qi, Hoi-Kwong Lo
The security of a standard bi-directional "plug & play" quantum key distribution (QKD) system has been an open question for a long time. This is mainly because its source is equiva…
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…
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…
