Bell nonlocality with directly generated telecom-band spin-photon entanglement
Dong-Yu Huang, Jian Wang, Xiao-Long Zhou +8
Quantum nonlocality, typically revealed through entanglement distribution across quantum networks, is a cornerstone of quantum information science. Long-distance distribution of en…
Loss and distinguishability effects in heralded entangled state generation with Gaussian resources
Yun-Long Cao, Xiao-Ye Xu, Wiwittawin Sukmas +2
The effects of optical loss and photon distinguishability on the heralded generation of entangled states based on Gaussian resources are quantitatively investigated. By incorporati…
Boosting Gaussian Boson Sampling using Optical Parametric Amplification Networks
Yukuan Zhao, Xiao-Ye Xu, Chuan-Feng Li +1
Gaussian Boson Sampling (GBS) provides a route toward demonstrating quantum computational advantage. However, optical loss, which reduces the entanglement in the system, can render…
High-yield engineering and identification of oxygen-related modified divacancies in 4H-SiC
Qi-Cheng Hu, Ji-Yang Zhou, Shuo Ren +9
Modified divacancies in the 4H polytype of silicon carbide (SiC) exhibit enhanced charge stability and spin addressability at room temperature, making them attractive for quantum a…
Integrated time-bin entangled quantum light source on a 4H-SiC microring chip
Hong Zeng, Bing-Cheng Yang, Yun-Ru Fan +16
Integrated time-bin-entangled photon-pair source with cavity-enhanced nonlinear optical processes is essential for quantum information technologies. However, microcavities with a h…
Experimental observation of entropic-singularity-induced nonadditive quantum communication in a qutrit platypus channel
Yu Guo, Bo-Xuan Wang, Xiao-Min Hu +4
The nonadditivity of channel capacity is a defining feature that distinguishes quantum communication from classical communication. In the quantum realm, the channel capacity is det…
