Quantum Error Correction via Tensor Networks
Jincheng Zhang
Abstract
Quantum error correction (QEC) is crucial for the reliable implementation of quantum computers, as qubits are extremely sensitive to environmental noise. Traditional approaches to QEC often suffer from computational complexity, particularly when scaling to larger qubit systems. This work explores the application of tensor networks as a novel method for representing and manipulating quantum error correction codes. We demonstrate that tensor networks provide a compact and efficient framework for encoding and decoding quantum information, potentially mitigating the scalability issues inherent in conventional QEC schemes. Specifically, we leverage the ability of tensor networks to represent the entanglement structure of codes, allowing for efficient simulation and decoding of noisy quantum computations. This approach offers a promising avenue for developing scalable QEC protocols. The core claim is that tensor networks offer a compact and efficient representation for quantum error correction codes. The core mechanism involves utilizing tensor networks to represent the entanglement structure of quantum error correction codes, enabling efficient simulation and decoding of noisy quantum computations.
