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…

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…
