A scheme to enhance the error-correcting capability of encoded quantum information

Han-Wei Wang, I.-M. Tsai, Chih-Neng Chung, Sy‐Yen Kuo

Published Oct 11, 2006• 2 citations

Abstract

In a noisy quantum channel, burst errors usually causes multiple bit-phase flips that are adjacent to each other (Vatan, Raichowdry and Anantram, 1999; Grassl and Beth, 2000). This effectively makes some quantum error-correcting codes to be unusable. In this paper, the concept of interleaving qubit transmission is proposed. By using the interleaving method in a quantum information transmission process, burst errors in a quantum channel are re-arranged into different time slots. This relocation makes the error bits non-adjacent and hence increases the probability of information recovery. Note that although this scheme enhances the error-correcting capability of the encoded quantum information, it does not increase the redundancy of the code, because only the qubit sequences are relocated. In addition to the interleaving scheme, implementation of the proposed scheme at the circuit level is also discussed in this paper.

Quantum Interleaver: Quantum Error Correction for Burst Error

Shiro Kawabata

The concept of quantum interleaver and a simple method of quantum burst-error correction is proposed. By using the quantum interleaver, any quantum burst-errors that have occurred spread over the interleaved code word, so that we can construct good quantum burst-error correcting codes without increasing the redundancy of the code. We also discuss the general method of constructing the quantum circuit for the quantum interleaver and the quantum network.

How to Combat Quantum Bursts of Errors Efficiently

Ying Guo, Guihua Zeng

To construct a quantum code with much error-correcting ability, the philosophy of the quantum interleaving is illustrated by introducing the block interleaving techniques. Quantum interleaving is a process to rearrange the qubits of several states of the same code so as to spread the same quantum errors over multiple states. Utilizing the interleaving technique, the concatenated k n -qubit code is constructed in this paper with more error-correcting ability than utilizing only one n -qubit quantum error-correcting code (QECC) without introducing the redundant qubits. It hence suggests an important way to design an quantum convolution code as the classical convolutional code has been constructed. For the application, the proposed quantum interleaving technique becomes an effective means to combat quantum bursts of errors by converting quantum bursts of errors into quantum random errors.

New Quantum Burst-Error Correcting Codes from Interleaving Technique

Quantum memory is essential for the development of many devices in quantum information processing, including a synchronization tool that can match the various processes in a quantum computer, a quantum gate that maintains the identity of any state, and a mechanism for converting predetermined photons into on-demand photons. Quantum memory can be used in many aspects, such as quantum computing and quantum communication. Continuous research and experiments have enabled quantum memory to realize the storage of qubits. On the other hand, interleaving techniques are used to deal with burst of errors. Many works from literature provide effective interleaving techniques for combating burst of errors by using classical error-correcting codes. However, to the best of our knowledge, little is known regarding interleaving techniques for combating cluster of errors in topological quantum error-correcting codes. Thenceforward, it is proposed in this work a new interleaving technique by using good toric quantum codes, namely Bombin and Martin-Delgado toric codes and another class of toric codes from literature which is described in this work. As a consequence, by applying this new interleaving method to such toric quantum codes, new quantum burst-error correcting codes are obtained which improve the coding gain. In addition to the proposed quantum interleaving technique improves such parameter, it can be used for burst-error correction in errors which are located, quantum data stored and quantum channels with memory.

Quantum Error Correction Redundancy Coding

Jincheng Zhang

This paper presents a novel approach to quantum error correction (QEC) utilizing redundancy coding, focusing on enhanced efficiency in quantum information transmission. The core claim revolves around designing multi-particle error-correcting codes to minimize the resource consumption associated with encoding and decoding. The proposed mechanism involves encoding information across multiple qubits, leveraging error detection and correction capabilities inherent in these codes. Crucially, the strategy optimizes the distribution of redundant qubits, significantly reducing unnecessary information redundancy. The research addresses the limitations of existing QEC schemes, which often rely on excessive redundancy, impacting transmission efficiency. This work demonstrates a pathway towards more practical and resource-conscious QEC, representing a key step toward reliable long-distance quantum communication. The primary goal is to reduce the overhead associated with error correction, making quantum information transfer more viable. This is achieved through a refined approach to redundancy, concentrating correction resources where they are most needed.
