摘要

Quantum entanglement,since proposed by Einstein,Podolsky and Rosen (EPR) [1] and further explored by Schr(o)dinger [2] in 1935,has always been the focus of quantum physics realm.The EPR paradox revealed the conflict between quantum theory and local realism.Almost 30 years later,in 1964,Bell first came up with the prototype of a family of inequalities,which was later called Bell inequality [3,4],to express certain limitation that every local classical hidden variable theory should follow up.Therefore,it could be used to distinguish the quantum theory from the local hidden variable theories.Experimental verifications on Bell inequality lasted for 40 years,until the loophole-free experiments was performed in 2015 [5].
