Reply to "comment on Geometric phases for mixed states during cyclic evolutions"
Li-Bin Fu, Jing-Ling Chen
We show that the geometric phase for mixed state during a cyclic evolution suggested in 2004 J. Phys. A 37 3699 is U(1) invariant and can be observed by nowaday techniques.
Geometric Phases for Mixed States during Cyclic Evolutions
Li-Bin Fu, Jing-Ling Chen
The geometric phases of cyclic evolutions for mixed states are discussed in the framework of unitary evolution. A canonical one-form is defined whose line integral gives the geomet…
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…
Maximal violation of Clauser-Horne-Shimony-Holt inequality for two qutrits
Li-Bin Fu, Jing-Ling Chen, Xian-Geng Zhao
Bell-Clauser-Horne-Shimony-Holt inequality (in terms of correlation functions) of two qutrits is studied in detail by employing tritter measurements. A uniform formula for the maxi…
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…
