Scrutinizing joint remote state preparation under decoherence

Abstract

Abstract This research examines the effect of an open system containing the squeezed generalized amplitude damping channel on the joint remote preparation quantum communication protocol using a maximally entangled two-qubit state. Our findings indicate that the fidelity of a quantum system in contact with a non-zero temperature thermal bath can be enhanced by varying the squeezing parameters. These parameters include the squeezing phase of the channel $$\Phi$$ Φ and the amount of squeezing of the channel r.
