Fiber-integrated Quantum Frequency Conversion for Long-distance Quantum Networking
Zhichuan Liao, Ao Shen, Lai Zhou +2
Signal photons emitted by quantum nodes typically fall outside the low-loss telecom window of optical fibers, leading to severe transmission losses. Quantum frequency conversion (Q…
Independent Optical Frequency Combs Powered 546 km Field Test of Twin-Field Quantum Key Distribution
Lai Zhou, Jinping Lin, Chengfang Ge +11
Owing to its repeater-like rate-loss scaling, twin-field quantum key distribution (TF-QKD) has repeatedly exhibited in laboratory its superiority for secure communication over reco…
Post-Measurement Pairing Quantum Key Distribution with Local Optical Frequency Standard
Chengfang Ge, Lai Zhou, Jinping Lin +3
The idea of post-measurement coincidence pairing simplifies substantially long-distance, repeater-like quantum key distribution (QKD) by eliminating the need for tracking the diffe…
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…
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…
Controlled entanglement source for quantum cryptography
Qiang Zeng, Haoyang Wang, Huihong Yuan +5
Quantum entanglement has become an essential resource in quantum information processing. Existing works employ entangled quantum states to perform various tasks, while little atten…
Ultra-narrowband interference circuits enable low-noise and high-rate photon counting for InGaAs/InP avalanche photodiodes
Yuanbin Fan, Tingting Shi, Weijie Ji +3
Afterpulsing noise in InGaAs/InP single photon avalanche photodiodes (APDs) is caused by carrier trapping and can be suppressed successfully through limiting the avalanche charge v…
Experimental Quantum Communication Overcomes the Rate-loss Limit without Global Phase Tracking
Lai Zhou, Jinping Lin, Yuan-Mei Xie +4
Secure key rate (SKR) of point-point quantum key distribution (QKD) is fundamentally bounded by the rate-loss limit. Recent breakthrough of twin-field (TF) QKD can overcome this li…
Twin-field quantum key distribution without optical frequency dissemination
Lai Zhou, Jinping Lin, Yumang Jing +1
Twin-field (TF) quantum key distribution (QKD) has rapidly risen as the most viable solution to long-distance secure fibre communication thanks to its fundamentally repeater-like r…
