Abstract: In this talk, I will discuss several recent advancements in error mitigation strategies for estimating expectation values of local observables, where we introduce a new Probabilistic Error Cancellation (PEC) estimator leveraging light-cone structures to drastically reduce sampling overhead. I will also describe our ‘shaded lightcone’ approach, which combines classical bounds on error channel influence on the expectation values to optimize the bias-variance trade-off, achieving up to a two-order-of-magnitude runtime reduction for circuits like 127-qubit Trotter circuits.
