Unlike conventional zero-noise extrapolation, whose measurement cost scales linearly with the number of circuits in a parameterized family, S-ZNE needs only constant measurement overhead regardless of how many circuits are involved. Theoretical analysis and numerical experiments on ground-state energy and quantum metrology tasks with up to 100 qubits show accuracy comparable to conventional zero-noise extrapolation, suggesting the approach could generalize to other quantum error mitigation protocols. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is surrogate-enabled zero-noise extrapolation (S-ZNE) in quantum error mitigation? S-ZNE is a quantum error mitigation technique that performs zero-noise extrapolation entirely on the classical side using classical learning surrogates instead of repeated quantum measurements. While conventional zero-noise extrapolation has measurement cost scaling linearly with the number of circuits in a parameterized family, S-ZNE requires only constant measurement overhead for the entire family, and numerical experiments on up to 100-qubit ground-state energy and quantum metrology tasks confirm accuracy comparable to conventional zero-noise extrapolation. _Researchers tracking advances in quantum error mitigation can follow developments like this on daily.dev._ ## Similar posts on daily.dev -
