Contribution

It introduces a novel scheme for creating NOON states in cavities using atomic interactions and two-photon resonances, advancing quantum state engineering techniques.

Findings

Successful generation of NOON states in cavity systems.

Atoms entangle two cavities via two-photon interactions.

Pure cavity states achieved through atomic state-dependent photon exchange.

Abstract

We show how NOON states may be generated entangling two cavities by passing atoms through them. The atoms interact with each cavity via two-photon resonant transitions. We take advantage of the fact that depending on the state the atom enter (excite or ground), it leaves or takes two photons per interaction and leaves the cavities in a pure state.
