Triangle Quantum Computing Seminar Series: Reliable High-Accuracy Error Mitigation for Large-Scale Quantum Circuits

Abstract: Hardware errors remain the primary obstacle to realizing the full potential of quantum computers. The current go-to approach for executing large-scale quantum circuits is error mitigation, which eliminates the impact of errors at the cost of additional runtime. Yet, most existing approaches either rely on uncontrolled heuristics or require prohibitive QPU time that makes them impractical for large-scale circuit execution. In this talk, I will introduce QESEM, a quantum error suppression and error mitigation software designed to deliver accurate and reliable results from large-scale quantum circuits. I will present recent results obtained with QESEM across diverse applications, and describe its core innovations and inner workings. Looking forward, I will argue that error mitigation methods will likely be the first to enable quantum advantage and will remain essential once error correction becomes practical. I will conclude with a perspective on QESEM's projected performance on near-term and future error-corrected devices, and its implications for scaling toward practical quantum advantage.
