W-state Analyzer and Multi-party Measurement-device-independent Quantum Key Distribution
Changhua Zhu, Feihu Xu, Changxing Pei
W-state is an important resource for many quantum information processing tasks. In this paper, we for the first time propose a multi-party measurement-device-independent quantum ke…
Photon-efficient quantum cryptography with pulse-position modulation
Tian Zhong, Feihu Xu, Zheshen Zhang +7
The binary (one-bit-per-photon) encoding that most existing quantum key distribution (QKD) protocols employ puts a fundamental limit on their achievable key rates, especially under…
Effect of source tampering in the security of quantum cryptography
Shi-Hai Sun, Feihu Xu, Mu-Sheng Jiang +3
The security of source has become an increasingly important issue in quantum cryptography. Based on the framework of measurement-device-independent quantum-key-distribution (MDI-QK…
Measurement-device-independent quantum communication with an untrusted source
Feihu Xu
Measurement-device-independent quantum key distribution (MDI-QKD) can provide enhanced security, as compared to traditional QKD, and it constitutes an important framework for a qua…
Discrete-variable measurement-device-independent quantum key distribution suitable for metropolitan networks
Feihu Xu, Marcos Curty, Bing Qi +2
We demonstrate that, with a fair comparison, the secret key rate of discrete-variable measurement-device-independent quantum key distribution (DV-MDI-QKD) with high-efficiency sing…
Experimental Quantum Fingerprinting
Feihu Xu, Juan Miguel Arrazola, Kejin Wei +6
Quantum communication holds the promise of creating disruptive technologies that will play an essential role in future communication networks. For example, the study of quantum com…
