Quantum key distribution over 658 km fiber with distributed vibration sensing
Jiu-Peng Chen, Chi Zhang, Yang Liu +11
Twin-field quantum key distribution (TF-QKD) promises ultra-long secure key distribution which surpasses the rate distance limit and can reduce the number of the trusted nodes in l…
Phase-Programmable Gaussian Boson Sampling Using Stimulated Squeezed Light
Han-Sen Zhong, Yu-Hao Deng, Jian Qin +23
The tantalizing promise of quantum computational speedup in solving certain problems has been strongly supported by recent experimental evidence from a high-fidelity 53-qubit super…
Superconducting microstrip single-photon detector with system detection efficiency over 90% at 1550 nm
Guang-Zhao Xu, Wei-Jun Zhang, Li-Xing You +9
Generally, a superconducting nanowire single-photon detector (SNSPD) is composed of wires with a typical width of ~100 nm. Recent studies have found that superconducting strips wit…
