Accuracy of a teleported trapped field state inside a single bimodal cavity

TL;DR

This paper presents a simplified scheme for teleporting superpositions of coherent states within a bimodal cavity, achieving high fidelity under realistic experimental conditions, and extends to teleportation between separate cavities.

Contribution

It introduces a practical teleportation method for superposed coherent states in bimodal cavities, with fidelity calculations based on current experimental capabilities.

Findings

Teleportation fidelity is high for mean photon numbers up to 1.5.

The scheme is applicable for teleportation between different cavities in a shared reservoir.

The approach simplifies existing protocols for cavity quantum state transfer.

Abstract

We propose a simplified scheme to teleport a superposition of coherent states from one mode to another of the same bimodal lossy cavity. Based on current experimental capabilities, we present a calculation of the fidelity that can be achieved, demonstrating accurate teleportation if the mean photon number of each mode is at most 1.5. Our scheme applies as well for teleportation of coherent states from one mode of a cavity to another mode of a second cavity, both cavities embedded in a common reservoir.
