A Single Fixed Shallow Circuit for Classical Shadows of Arbitrary n-Qubit States
Yu Wang, Xiuwu Zhu
Classical shadows extract quantum properties from reusable classical records, typically obtained through randomized measurement settings. Although individual settings may be shallo…

Uniformly Stable Minimal Weyl--Heisenberg Measurements Approaching the SIC Benchmark
Xiuwu Zhu, Yu Wang
Informational completeness (IC) guarantees that an inverse exists, not that it is statistically well conditioned. For minimal rank-one Weyl--Heisenberg (WH) measurements, covarianc…

Noncommutative maximal differential transforms associated to averaging operators
Shaohong Liang, Yu Wang, Bang Xu +1
In this paper, we establish the noncommutative maximal weak type and strong type estimates for the family of operators , defined by $$T_Nf=\sum_{k=N_1}^{N_…
