Memory-Assisted Nonlocal Interferometer Towards Long-Baseline Telescopes
Bin Wang, Xi-Yu Luo, Bo-Feng Gao +12
Quantum networks and remote quantum entanglement serve as vital future quantum communication resources with broad applicability. A key direction lies in extending the baseline of o…
Single-photon interference over 8.4 km urban atmosphere: towards testing quantum effects in curved spacetime with photons
Hui-Nan Wu, Yu-Huai Li, Bo Li +8
The emergence of quantum mechanics and general relativity has transformed our understanding of the natural world significantly. However, integrating these two theories presents imm…
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…
Experimental single-photon quantum key distribution surpassing the fundamental coherent-state rate limit
Yang Zhang, Xing Ding, Yang Li +17
Single-photon sources are essential for quantum networks, enabling applications ranging from quantum key distribution (QKD) to the burgeoning quantum internet. Despite the remarkab…
Pure-state photon-pair source with a long coherence time for large-scale quantum information processing
Bo Li, Yu-Huai Li, Yuan Cao +2
The Hong-Ou-Mandel interference between independent photons plays a pivotal role in the large-scale quantum networks involving distant nodes. Photons need to work in a pure state f…
Quantum Random Number Generation with Uncharacterized Laser and Sunlight
Yu-Huai Li, Xuan Han, Yuan Cao +8
The entropy or randomness source is an essential ingredient in random number generation. Quantum random number generators generally require well modeled and calibrated light source…
