Quantum teleportation between "particle-like" and "field-like" qubits using hybrid entanglement under decoherence effects

Abstract

We study quantum teleportation between two different types of optical qubits, one of which is "particle-like" and the other "field-like," via hybrid entangled states under the effects of decoherence. We find that teleportation from particle-like to field-like qubits can be achieved with a higher fidelity than that in the opposite direction. However, teleportation from field-like to particle-like qubits is found to be more efficient in terms of the success probabilities. Our study shows that the direction of teleportation should be considered an important factor in developing optical hybrid architectures for quantum information processing.
