Transmitter-device-independent quantum key distribution
Qiang Zeng, Abhishek Mishra, Haoyang Wang +1
Transmitter-side device dependence is a longstanding yet implicit problem in quantum key distribution (QKD), in contrast to the thoroughly addressed measurement-side case. Quantum…
A Directly Modulated Laser Platform for High-Dimensional Quantum Key Distribution
Yang Zhou, Xing-Yu Zhou, Shu-Fan Wu +3
High-dimensional quantum key distribution (HD-QKD) offers a promising approach to enhance secret key rates beyond conventional binary-encoded QKD, addressing the growing demand for…
High-Performance Fully Passive Discrete-State Continuous-Variable Quantum Key Distribution With Local Local Oscillator
Yu Zhang, Xuyang Wang, Chenyang Li +5
We propose and demonstrate a fully passive discrete-state continuous-variable quantum key distribution (CV-QKD), which can eliminate all modulator side channels on the source side,…
Steering nonlocality in high-speed telecommunication system without detection loophole
Qiang Zeng, Huihong Yuan, Haoyang Wang +2
Nonlocal correlation represents the key feature of quantum mechanics, and is an exploitable resource in quantum information processing. However, the loophole issues and the associa…
Bright Heralded Single-Photon Source Saturating Theoretical Single-photon Purity
Haoyang Wang, Huihong Yuan, Qiang Zeng +3
Single-photon source is the cornerstone for modern quantum information processing. The present work derives the theoretical limit of single-photon purity for general parametric her…
