  7. Abstract:
  8. In this investigation has been tried to indagate the Bell’s inequality both theoretically and experimentally. This inequality published by John Bell in 1964 on the EPR argument. In the EPR argument they reasonably deduced that quantum mechanics with the wave function interpretation is incomplete (but proposing correct results), so we must looking for a deterministic and more fundamental and underlying theory than common quantum mechanics, the alternative theory shall contain Reality and Locality assumptions and also could produce current quantum mechanics results. Afterward, scientific probation started for finding a deterministic theory that including hidden variables, infact supplement variables inserted in the theory to obtain most complete interpretation. Bell in 1964 derived an inequality under locality and reality assumptions which classical correlation functions involved, then proved a deterministic quantum mechanics that accompanied by supplemnt hidden variables, can not satisfy all the present quantum mechanics predictions. In present research, has been probed to explain several experimental attempts to show violation and inconsistency of Bell’s inequality (Generalized cases, e.g. CHSH & CH, Mermin inequality etc.) with experimental facts which truly adapt to current quantum mechanics. As final conclusion a new inequality has derived under reality and non-locality assumptions (Not locality at this time) and shown that quantum mechanics predictions concurs and adapts with the new inequality so we deduced that non-locality is an implicit conception in quantum mechanics and shall be taken into our consideration for furthur explorations
