Two different types of optical hybrid qubits for teleportation in a lossy environment

TL;DR

This paper compares two types of optical hybrid qubits for quantum teleportation in lossy environments, showing that vacuum-single photon hybrid qubits are more robust than polarization-based hybrids in terms of fidelity and success probability.

Contribution

It introduces and evaluates two different hybrid qubit types for teleportation, demonstrating the superior robustness of vacuum-single photon hybrids under photon loss.

Findings

Vacuum-single photon hybrid qubits outperform polarization hybrids in lossy conditions.

Hybrid qubits with vacuum and single-photon states show higher teleportation fidelity.

Success probabilities are higher for vacuum-single photon hybrid qubits in lossy environments.

Abstract

We investigate the performance of quantum teleportation under a lossy environment using two different types of optical hybrid qubits. One is the hybrid of the vacuum and single-photon states with coherent states and the other is the hybrid of polarized single-photon states with coherent states. We have shown that the hybrid qubit using vacuum and single-photon states is generally more robust to photon loss effects compared to the one using the photon polarization with respect to fidelities and success probabilities of quantum teleportation.
