We study the tests of the Bell-CHSH & CH inequalities by superposition of two coherent states (ı/2 out of phase), a class of non-Gaussian state, using photon parity and on/off measurements. Large violations of the Bell-type inequalities have been observed theoretically confirming the interpretation and validity of quantum mechanics against the local-realistic theories.
