15:30-17:00 Lecture 6Abstract:
Quantum Error Mitigation (QEM) offers a practical approach to reducing
errors in noisy intermediate-scale quantum (NISQ) devices without requiring
the encoding of qubits. In this seminar, I will begin by discussing the
fundamentals of noise modeling in quantum systems, followed by an overview
of QEM techniques, including extrapolation, probabilistic error
cancellation (PEC), virtual distillation, quantum subspace expansion, and
Clifford data regression. Next, I will present advanced QEM methods, such
as the stochastic PEC approach, which mitigates the effects of Lindblad
terms in Lindblad master equations and the generalized quantum subspace
expansion, which is a unified framework of QEM. I will also explore recent
research on the information-theoretic analysis of QEM, shedding light on
its fundamental limits and connections to non-Markovian dynamics.
Furthermore, I will discuss studies combining QEM with quantum error
correction to enhance the reliability of computations in the early
fault-tolerant quantum computing era. Lastly, I will highlight the
relevance of hybrid tensor networks, particularly their connections to
quantum subspace expansion techniques.
