Remarks on Bell’s Inequality

Authors: Zhengjun Cao, Lihua Liu


Quantum entanglement is of great importance to quantum cryptography and computation. So far, all experimental demonstrations of entanglement are designed to check Bell’s inequality which is based on Bell’s formulation for EPR paradox. In this note, we specify the assumptions needed in Bell’s mathematical argument. We then show the contradictions among these assumptions. As a result, it becomes very easy to see that Bell’s inequality is trivial.
