Analysis of the Bell-type inequalities on the IBM's open-access quantum computer

Abstract

We have performed quantum mechanical calculations of the Bell's and the Clauseer-Horne-Shimony-Holt inequalities for the Bell's states, showing that they are violated by these en-tangled states. We have also used the open-access IBM's quantum computer to prepare the Bell's states and to engineer the quantum circuits to experimentally measure the inequalities finding good agreement with the quantum calculations. We have also checked that product states, which are non-entangled, fulfill the inequalities.
