Factoring integers with sublinear resources on a superconducting quantum processor

Bao Yan, Ziqi Tan, Shijie Wei +21

Shor's algorithm has seriously challenged information security based on public key cryptosystems. However, to break the widely used RSA-2048 scheme, one needs millions of physical…

Upper security bounds for coherent-one-way quantum key distribution

Javier González-Payo, Róbert Trényi, Weilong Wang +1

The performance of quantum key distribution (QKD) is severely limited by multi-photon pulses emitted by laser sources due to the photon-number splitting attack. Coherent-one-way (C…

Measurement-Device-Independent Quantum Key Distribution with Leaky Sources

Weilong Wang, Kiyoshi Tamaki, Marcos Curty

Measurement-device-independent quantum key distribution (MDI-QKD) can remove all detection side-channels from quantum communication systems. The security proofs require, however, t…

Finite-key security analysis for quantum key distribution with leaky sources

Weilong Wang, Kiyoshi Tamaki, Marcos Curty

Security proofs of quantum key distribution (QKD) typically assume that the devices of the legitimate users are perfectly shielded from the eavesdropper. This assumption is, howeve…

Experimental measurement-device-independent quantum digital signatures over a metropolitan network

Hua-Lei Yin, Wei-Long Wang, Yan-Lin Tang +16

Quantum digital signatures (QDS) provide a means for signing electronic communications with informationtheoretic security. However, all previous demonstrations of quantum digital s…

Universally-composable finite-key analysis for efficient four-intensity decoy-state quantum key distribution

Haodong Jiang, Ming Gao, Bao Yan +2

We propose an efficient four-intensity decoy-state BB84 protocol and derive concise security bounds for this protocol with the universally composable finite-key analysis method. Co…

Experimental Passive Decoy-State Quantum Key Distribution

Qi-Chao Sun, Wei-Long Wang, Yang Liu +8

The decoy-state method is widely used in practical quantum key distribution systems to replace ideal single photon sources with realistic light sources by varying intensities. Inst…

Effect of imperfect Faraday mirrors on security of a Faraday-Michelson quantum cryptography system

Wang Weilong, Gao Ming, Ma Zhi

The one-way Faraday-Michelson system is a very useful practical quantum cryptography system where Faraday mirrors(FMs) play an important role. In this paper we analyze the security…

Decoy-state quantum key distribution with biased basis choice

Zhengchao Wei, Weilong Wang, Zhen Zhang +3

We propose a quantum key distribution scheme that combines a biased basis choice with the decoy-state method. In this scheme, Alice sends all signal states in the basis and dec…
