Entangled coherent states and violations of Bell-CHSH inequalities
Philipe De Fabritiis, Fillipe M. Guedes, Giovani Peruzzo +1
Three classes of entangled coherent states are employed to study the Bell-CHSH inequality. By using pseudospin operators in infinite dimensional Hilbert spaces, four dichotomic ope…

Entanglement and maximal violation of the CHSH inequality in a system of two spins j: a novel construction and further observations
Giovani Peruzzo, Silvio Paolo Sorella
We study the CHSH inequality for a system of two spin particles, for generic . The CHSH operator is constructed using a set of unitary, Hermitian operators $\left\{ A_{1},A_…
