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

Abstract: As quantum processors approach regimes that challenge the best available classical methods, the ability to handle errors becomes critical for unlocking their full potential. Error mitigation is essential for obtaining accurate results from large scales on both today's devices and future error-corrected architectures. 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. I will also discuss how integrating error-mitigated quantum processors with high-performance classical computing further extends the range and scale of accessible use-cases. Looking ahead, I will argue that error mitigation methods will likely be the first to enable quantum advantage and will remain essential once error correction becomes viable. 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.
