Bell's and Mermin's inequalities, entangled coherent states and unitary operators

Abstract

We elaborate on the recent proposal of employing unitary operators in Quantum Mechanics. The Bell and Mermin inequalities for entangled coherent states are scrutinized by making use of the unitary displacement operators. A violation of the Mermin inequality close to the maximum allowed value is reported, in agreement with the existing literature.
