Efficient Identification the Inequivalence of Mutually Unbiased Bases via Finite Operators
Jianxin Song, Zhen-Peng Xu, Changliang Ren
The structural characterization of high-dimensional mutually unbiased bases (MUBs) by classifying MUBs subsets remains a major open problem. The existing methods not only fail to c…

Quantum-to-Classical Transition via Single-Shot Generalized Measurements
Zhenyu Xu
We establish an operational connection between discrete rounds of generalized measurements and continuous-time decoherence, with an explicit correspondence between the number of me…

Experimental Certification of Quantum Measurements with Maximally Mixed States
Jia-He Liang, Ze-Yan Hao, Jia-Kun Li +6
So far, certifying quantum devices from their input-output statistics, under minimal assumptions, required the preparation of specific pure quantum states. Recently, Xu et al. [Phy…
