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…

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…
