Maximal violation of Clauser-Horne-Shimony-Holt inequality for four-level systems
Li-Bin Fu, Jing-Ling Chen, Shi-Gang Chen
Clauser-Horne-Shimony-Holt inequality for bipartite systems of 4-dimension is studied in detail by employing the unbiased eight-port beam splitters measurements. The uniform formul…

Understanding Quantum Entanglement of Bipartite System Based on Bell Inequality
Li-Bin Fu, Jing-Ling Chen, Xian-Geng Zhao +1
We present an alternative definition of quantum entanglement for bipartite system based on Bell inequality and operators' noncommutativity. A state is said to be entangled, if the…
