Quantum Communication With Polarization-Encoded Qubit Using Quantum Error Correction

Abstract

One of the most promising physical properties for implementation of quantum technology is light polarization. However, since light polarization is a fragile property, the use of quantum error correction (QEC) is a crucial issue in order to make quantum information over optical network feasible. In this direction, this paper discusses optical setups for quantum error correction in quantum communication setups based on light polarization. In particular, we show how to use the QEC setup to provide error-free entanglement distribution and its use in an error-free probabilistic teleportation setup. Then, we discuss the performance of the error-correction setup in a very noisy channel. Finally, we show that the same QEC setup can also be used to correct bipartite of qubit states.

Systems of quantum communication with linear optical

Daniel Barbosa de Brito

In this dissertation it is considered a quantum error correction system for coherent states of light and a complete optical system for probabilistic teleportation of single-photon polarization encoded qubit. Initially, the quantum error correction with the use of redundancy is analyzed. After that, it is presented a form of error correction using time-bin qubit without redundancies. Based on this last approach, a passive quantum error correction system, that is, without external control and synchronization, for quantum communication system employing coherent states, using only linear optical devices, is proposed. It is shown that the quantum error correction system also works for bipartite states of qubits. Following, the teleportation of quantum states is analyzed and an optical system for probabilistic teleportation of single-photon polarization encoded qubit, using only linear optical devices, is proposed. Finally, the error correction and teleportation topics are put together in the proposal of a probabilistic teleportation system using an error correction system for distribution of the entangled pair of photons

基于量子纠缠的纠错码设计

Jincheng Zhang

Quantum information is increasingly vital for modern technologies, including secure communication and advanced computation. However, the fragile nature of quantum states makes them susceptible to errors during transmission and storage. This paper proposes a novel quantum error correction (QEC) scheme based on the principle of quantum entanglement, aiming to significantly enhance the security of quantum communication. We detail the design of a QEC protocol utilizing entangled qubit states to detect and correct errors, offering a promising pathway toward building robust quantum networks. The core claim is that this method can achieve high error correction rates and secure quantum communication using the unique properties of entanglement.

Linear optical setups for active and passive quantum error correction in polarization encoded qubits

José Cláudio do Nascimento, Fábio Alencar Mendonça, Rubens Viana Ramos

In this work, we present active and passive linear optical setups for error correction in quantum communication systems that employ polarization of single-photon and mesoscopic coherent states. The proposed systems are analytically analysed and their applications in quantum communication systems are described. In particular, we show a security analysis of a QKD system employing the active error correction system when an eavesdropper uses the Fuchs–Peres–Brandt attack.

Error-free optical quantum communication

Dik Bouwmeester

An optical scheme for the reliable transfer of quantum information through a noisy quantum channel is proposed. The scheme is inspired by quantum error-correction protocols, but it avoids the currently infeasible requirement for a controlled-NOT operation between single photons. The quantum communication scheme presented here rejects single bit-flip errors instead of correcting them and combines quantum-measurement properties of three-particle entangled (GHZ) states with properties of quantum teleportation.
