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…
Quantifying information flow in quantum processes
Leonardo S. V. Santos, Zhen-Peng Xu, Jyrki Piilo +1
We present a framework for quantifying information flow within general quantum processes. For this purpose, we introduce the signaling power of quantum channels and discuss its rel…
Certifying sets of quantum observables with any full-rank state
Zhen-Peng Xu, Debashis Saha, Kishor Bharti +1
We show that some sets of quantum observables are unique up to an isometry and have a contextuality witness that attains the same value for any initial state. We prove that these t…
