Abstract

This paper investigates the potential of utilizing topological protection for quantum qubit storage, addressing a critical challenge in the development of practical quantum computing. Current approaches to mitigating decoherence in qubits often rely on physical isolation, which can be complex and introduce new vulnerabilities. This work proposes a novel strategy leveraging anyons within topological insulators to provide robust protection against decoherence. The core concept involves encoding quantum information using the non-Abelian braiding of anyons, inherently safeguarding against local perturbations. We explore the theoretical framework, detailing the mechanisms and potential challenges associated with this approach. This research highlights a promising alternative for achieving enhanced qubit storage stability and contributes to the advancement of topologically protected quantum computing. The key formulas and mathematical notations are presented in plain text.
