Findings

Superposition states can be formed without nonlinear effects.

Yurke-Stoler and cat states are specific examples of the general superposition.

Abstract

We report the formation of a general superposition of coherent states in exact analytical solution of the Schrodingers equatin for atom-photon interaction by taking into account the role of virtual photons. Despite some known superposition of quantum states, the general superposition state introduced in this letter constructed without any nonlinear effect. The Yurke- Stoler state and its special cases, the even and odd cat states, obtained as some simple examples of the method. A general experimental setup is proposed to realize a variety of superposition states.
