A measurement-device-independent quantum key distribution network using optical frequency comb
Wenhan Yan, Xiaodong Zheng, Wenjun Wen +5
Quantum key distribution (QKD), which promises secure key exchange between two remote parties, is now moving toward the realization of scalable and secure QKD networks (QNs). Fully…
Quantum walks of correlated photons in non-Hermitian photonic lattices
Mingyuan Gao, Chong Sheng, Yule Zhao +6
Entanglement entropy characterizes the correlation of multi-particles and unveils the crucial features of open quantum systems. However, the experimental realization of exploring e…
Observation of quantum nonlocality in Greenberger-Horne-Zeilinger entanglement on a silicon chip
Leizhen Chen, Bochi Wu, Liangliang Lu +4
Nonlocality is the defining feature of quantum entanglement. Entangled states with multiple particles are of crucial importance in fundamental tests of quantum physics as well as i…
Polarization-entangled quantum frequency comb from a silicon nitride microring resonator
Wenjun Wen, Wenhan Yan, Chi Lu +5
Integrated microresonator facilitates the realization of quantum frequency comb (QFC), which provides a large number of discrete frequency modes with broadband spectral range and n…
