5-GHz chip-based quantum key distribution with 1Mbps secure key rate over 150 km
Guo-Wei Zhang, Sheng-Teng Zheng, You Xiao +16
Quantum key distribution (QKD) enables secure communication by harnessing the fundamental principles of quantum physics, which inherently guarantee information-theoretic security a…
Experimental Multi-Dimensional Side-Channel-Secure Quantum Key Distribution
Hao Dong, Cong Jiang, Di Ma +8
Quantum key distribution (QKD) theoretically provides unconditional security between remote parties. However, guaranteeing practical security through device characterisation alone…
Entangling quantum memories over 420 km in fiber
Xi-Yu Luo, Chao-Yang Wang, Ming-Yang Zheng +17
Long-distance entanglement is pivotal for quantum communication, distributed quantum computing and sensing. Significant progresses have been made in extending the distribution dist…
Free-Space Twin-Field Quantum Key Distribution
Yu-Huai Li, Ting Zeng, Min-Yan Wang +22
Twin-field quantum key distribution (TF-QKD) elevates the secure key rate from a linear to a square-root dependence on channel loss while preserving measurement-device-independent…
Experimental practical quantum tokens with transaction time advantage
Yang-Fan Jiang, Adrian Kent, Damián Pitalúa-GarcÃa +10
Quantum money is the first invention in quantum information science, promising advantages over classical money by simultaneously achieving unforgeability, user privacy, and instant…
