This research introduces a novel protocol for estimating quantum fidelity between known target states and unknown prepared states using sublinear numbers of Pauli basis measurements. By achieving precision $\varepsilon$ with significantly fewer resources than previous methods, the study advances the efficiency of state verification in quantum computing architectures. The work directly addresses resource optimization challenges critical for scaling near-term quantum devices.

Sublinear Copies Suffice for Fidelity Estimation with Pauli Measurements

arXivSeptember 30, 20261 min read

arXiv:2609.35547v1 Announce Type: new Abstract: We present a protocol that estimates the quantum fidelity, up to precision $\varepsilon$, between a known target state and unknown lab-prepared state with sublinear, $o(d^{0.9908}/\varepsilon^2)$, number of Pauli basis measurements.
