Breaking the Rate-Loss Bound of Quantum Key Distribution with Asynchronous Two-Photon Interference
Yuan-Mei Xie, Yu-Shuo Lu, Chen-Xun Weng +7
Twin-field quantum key distribution can overcome the secret key capacity of repeaterless quantum key distribution via single-photon interference. However, to compensate for the cha…
Scalable High-Rate Twin-Field Quantum Key Distribution Networks without Constraint of Probability and Intensity
Yuan-Mei Xie, Chen-Xun Weng, Yu-Shuo Lu +4
Implementation of a twin-field quantum key distribution network faces limitations, including the low tolerance of interference errors for phase-matching type protocols and the stri…
Long-distance twin-field quantum key distribution with entangled sources
Bing-Hong Li, Yuan-Mei Xie, Zhao Li +4
Twin-field quantum key distribution (TFQKD), using single-photon-type interference, offers a way to exceed the rate-distance limit without quantum repeaters. However, it still suff…
Finite-key Analysis for Quantum Conference Key Agreement with Asymmetric Channels
Zhao Li, Xiao-Yu Cao, Chen-Long Li +4
As an essential ingredient of quantum networks, quantum conference key agreement (QCKA) provides unconditional secret keys among multiple parties, which enables only legitimate use…
Experimental quantum secure network with digital signatures and encryption
Hua-Lei Yin, Yao Fu, Chen-Long Li +6
Cryptography promises four information security objectives, namely, confidentiality, integrity, authenticity, and non-repudiation, to support trillions of transactions annually in…
Simple security proof of coherent-one-way quantum key distribution
Rui-Qi Gao, Yuan-Mei Xie, Jie Gu +5
Coherent-one-way quantum key distribution (COW-QKD), which requires a simple experimental setup and has the ability to withstand photon-number-splitting attacks, has been not only…
Efficient Quantum Digital Signatures without Symmetrization Step
Yu-Shuo Lu, Xiao-Yu Cao, Chen-Xun Weng +5
Quantum digital signatures (QDS) exploit quantum laws to guarantee non-repudiation, unforgeability and transferability of messages with information-theoretic security. Current QDS…
Secure and practical multiparty quantum digital signatures
Chen-Xun Weng, Yu-Shuo Lu, Rui-Qi Gao +6
Quantum digital signatures (QDSs) promise information-theoretic security against repudiation and forgery of messages. Compared with currently existing three-party QDS protocols, mu…
Homodyne Detection Quadrature Phase Shift Keying Continuous-Variable Quantum Key Distribution with High Excess Noise Tolerance
Wen-Bo Liu, Chen-Long Li, Yuan-Mei Xie +7
Discrete-modulated continuous-variable quantum key distribution with homodyne detection is widely recognized for its ease of implementation, efficiency with respect to error correc…
