Decoherence Effect and Beam Splitters for Production of Quasi-Amplified Entangled Quantum Optical Light

Abstract

We let a set of beam splitters of vacuum mode with a chosen transmittance parameter η in interaction with a separable coherent states. This model induces the production of an attenuated quantum channels based on entangled optical states. Indeed, the decoherence effect is exploited positively here to generate such kind of quantum channels. Next, the amplitude damping and the entanglement amount of these produced channels are enhanced thereafter by a probabilistic quasi amplification process using again a 50:50 beam splitter.
