Performance Analysis of Quantum Error Correction Codes in Noisy Intermediate-Scale Quantum (NISQ) Cryptography Authors

Abstract

Quantum Error Correction Codes (QECCs) are essential for mitigating errors in Noisy Intermediate-Scale Quantum (NISQ) devices, which are prone to decoherence and operational imperfections. This study evaluates the performance of various QECCs, including surface codes, stabilizer codes, and low-density parity-check (LDPC) codes, in the context of NISQ-based cryptographic applications. Through numerical simulations and comparative analysis, we assess their error suppression capabilities, resource overhead, and computational feasibility under realistic noise models. Our findings highlight the trade-offs between error correction efficiency and implementation complexity, providing insights into optimizing QECCs for practical quantum cryptography in the NISQ era.
