- Abstract
- Aspect et al.’s experiment[5] verified the violation of Bell inequality and the validity of quantum mechanics rather than local hidden-variables theory. In this manuscript, we will show that there exists difference between definitions for the expectation value using the probability distribution in Bell’s inequality and the expectation value in quantum mechanics. It is this difference that leads to the controversy between the expectation values in quantum mechanics and Bell’s inequality. The expectation values in quantum mechanics should obey their own inequality.
