Discrete-phase-randomized coherent state source and its application in quantum key distribution
Zhu Cao, Zhen Zhang, Hoi-Kwong Lo +1
Coherent state photon sources are widely used in quantum information processing. In many applications, such as quantum key distribution (QKD), a coherent state is functioned as a m…
Measurement-device-independent quantum cryptography
Feihu Xu, Marcos Curty, Bing Qi +1
In theory, quantum key distribution (QKD) provides information-theoretic security based on the laws of physics. Owing to the imperfections of real-life implementations, however, th…
Experimental quantum key distribution with source flaws
Feihu Xu, Kejin Wei, Shihan Sajeed +6
Decoy-state quantum key distribution (QKD) is a standard technique in current quantum cryptographic implementations. Unfortunately, existing experiments have two important drawback…
Protocol choice and parameter optimization in decoy-state measurement-device-independent quantum key distribution
Feihu Xu, He Xu, Hoi-Kwong Lo
Measurement-device-independent quantum key distribution (MDI-QKD) has been demonstrated in both laboratories and field-tests using attenuated lasers combined with the decoy-state t…
No Superluminal Signaling Implies Unconditionally Secure Bit Commitment
H. F. Chau, C. -H. Fred Fung, H. -K. Lo
Bit commitment (BC) is an important cryptographic primitive for an agent to convince a mutually mistrustful party that she has already made a binding choice of 0 or 1 but only to r…
