Bayesian Phase Stabilization at the Shot-Noise Limit for Scalable Quantum Networks
Guang-Cheng Liu, Chao-Hui Xue, Fa-Xi Chen +11
High-precision optical phase stabilization in quantum networks is fundamentally constrained by the strict photon-flux and duty-cycle limits required to avoid disturbing fragile qua…
1-Mbps Twin-Field Quantum Key Distribution over 200 km Using Independent Dissipative Kerr Solitons
Hao Dong, Tian-Jiao Zhang, Yan-Wei Chen +10
Twin-field quantum key distribution (TF-QKD) dramatically enhances the secure key rate (SKR) over inter-city distances through its square-root scaling. Further improvements in aggr…
Electrically pumped ultra-efficient quantum frequency conversion on thin film lithium niobate chip
Xina Wang, Xu-Feng Jiao, Bo Cao +5
Quantum frequency conversion (QFC) plays a crucial role in constructing seamless interconnection between quantum systems operating at different wavelengths. To advance future quant…
Ultrabright Entanglement Based Quantum Key Distribution over a 404 km Optical Fiber
Shi-Chang Zhuang, Bo Li, Ming-Yang Zheng +14
Entangled photons are crucial resources for quantum information processing. Here, we present an ultrabright polarization-entangled photon source based on a periodically poled lithi…
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…
