Decoy state measurement-device-independent quantum key distribution based on the Clauser-Horne-Shimony-Holt inequality
Chun-Mei Zhang, Mo Li, Hong-Wei Li +10
The measurement-device-independent quantum key distribution (MDI-QKD) protocol is proposed to remove the detector side channel attacks, while its security relies on the assumption…
Field and long-term demonstration of a wide area quantum key distribution network
Shuang Wang, Wei Chen, Zhen-Qiang Yin +20
A wide area quantum key distribution (QKD) network deployed on communication infrastructures provided by China Mobile Ltd. is demonstrated. Three cities and two metropolitan area Q…
Mismatched-basis statistics enable quantum key distribution with uncharacterized qubit sources
Zhen-Qiang Yin, Chi-Hang Fred Fung, Xiongfeng Ma +6
In the postprocessing of quantum key distribution, the raw key bits from the mismatched-basis measurements, where two parties use different bases, are normally discarded. Here, we…
Tight finite-key analysis for passive decoy-state quantum key distribution under general attacks
Chun Zhou, Wan-su Bao, Hong-wei Li +5
For quantum key distribution (QKD) using spontaneous parametric-down-conversion sources (SPDCSs), the passive decoy-state protocol has been proved to be efficiently close to the th…
Properties of dimension witnesses and their semi-definite programming relaxations
Piotr Mironowicz, Hong-Wei Li, Marcin Pawłowski
In this paper we develop a method for investigating semi-device-independent randomness expansion protocols that was introduced in [Li et al., Phys. Rev. A , 020302(R)…
Security of modified Ping-Pong protocol in noisy and lossy channel
Yun-Guang Han, Zhen-Qiang Yin, Hong-Wei Li +4
The "Ping-Pong" (PP) protocol is a two-way quantum key protocol based on entanglement. In this protocol, Bob prepares one maximally entangled pair of qubits, and sends one qubit to…
