Probing Mermin's inequalities violations through pseudospin operators

Quantum Physics 2023-09-20 v1

Abstract

The violation of Mermin's inequalities is analyzed by making use of two different Bell setups built with pseudospin operators. Employing entangled states defined by means of squeezed and coherent states, the expectation value of Mermin's polynomials MnM_n is evaluated for n=3n=3 and n=4n=4. In each case, we analyze the correlator Mn\langle M_n \rangle and identify the set of parameters leading to the violation of Mermin's inequalities and to the saturation of the bound predicted by Quantum Mechanics.
