Abstract

This paper explores the potential of topological photonics for realizing long-distance quantum bit (qubit) interconnection, a critical step towards building scalable and reliable quantum computers. Conventional approaches to quantum communication face significant challenges due to photon loss in optical fibers, limiting the transmission distance and fidelity of quantum information. We investigate how the unique properties of topological photonics, specifically the utilization of light propagation within topological defects, can circumvent these limitations. The core concept involves harnessing robust, protected edge states within photonic lattices, enabling entanglement distribution and quantum communication over significantly extended distances without the deleterious effects of direct photon scattering. This paper details the theoretical framework, focusing on key aspects such as the creation and manipulation of these topological states, and the potential for building interconnected qubit networks. We present a framework for understanding the advantages of this approach and highlight key research directions.

Quantum error correction (QEC) is crucial for realizing practical quantum computation. However, the fragility of quantum states to environmental noise poses a significant challenge. This work proposes a novel approach to QEC utilizing topological qubits encoded within photonic networks. Topological qubits, characterized by their robust topological properties, offer inherent protection against local perturbations, making them ideal candidates for QEC. This architecture combines the advantages of both topological protection and the scalability offered by photonic networks. We present a theoretical framework for implementing a specific QEC code based on these principles, detailing the encoding process, error detection, and correction operations.
