Classical shadows with symmetries
Classical shadows (CS) have emerged as a powerful way to estimate many properties of
quantum states based on random measurements and classical post-processing. In their …

Classical Shadows with Improved Median-of-Means Estimation
The classical shadows protocol, introduced by Huang et al.[Nat. Phys. 16, 1050 (2020)],
makes use of the median-of-means (MoM) estimator to efficiently estimate the expectation …
