Extended Bell inequality and maximum violation
Yan Gu, Haifeng Zhang, Zhigang Song +2
The original formula of Bell inequality (BI) in terms of two-spin singlet has to be modified for the entangled-state with parallel spin polarization. Based on classical statistics…

Quantum Non-localities and Correlation-Measurement-Induced Berry Phases for Spin-Singlet States
Zhigang Song, J. -Q. Liang, L. -F. Wei
We in this Letter derive analytic formulas of Bell correlations in terms of quantum probability statistics under the assumption of measuring outcome-independence. For a spin-1/2 si…
