Quantum Error Mitigation via Entanglement Suppression

Publisher

Abstract

Quantum error mitigation (QEM) is a crucial area of research for realizing fault-tolerant quantum computation. While various QEM techniques have been developed, many rely on classical post-processing of quantum measurements, which can introduce their own biases and limitations. This paper proposes a novel hardware error mitigation strategy leveraging the inherent properties of quantum entanglement and its susceptibility to environmental decoherence. The core idea is to actively suppress quantum decoherence, specifically targeting the entanglement that contributes significantly to error propagation in quantum computations. We formulate a control scheme that precisely modulates environmental parameters to minimize the detrimental effects of entanglement-induced decoherence. The effectiveness of this approach is demonstrated through a theoretical analysis, outlining the potential for significant error reduction without relying on complex post-processing algorithms. The key benefit lies in a proactive, hardware-level approach to mitigating errors, offering a potentially more robust and efficient solution compared to post-processing methods. This work establishes a foundational framework for future research in entanglement-aware QEM.
