Findings

Squeezed baths improve superposition state creation.

Numerical solutions of the master equation are presented.

Squeezed reservoirs outperform thermal ones in this context.

Abstract

The evolution of a single mode of the electromagnetic field interacting with a squeezed bath in a Kerr medium is considered. The solution of the corresponding master equation is given numerically. It is argued that the creation of a superposition state (Schr\"odinger's cat) is better achieved in presence of a squeezed reservoir than of a thermal one.
