Probability density functions of quantum mechanical observable uncertainties
Lin Zhang, Jinping Huang, Jiamei Wang +1
We study the uncertainties of quantum mechanical observables, quantified by the standard deviation (square root of variance) in Haar-distributed random pure states. We derive analy…
Spectral density of mixtures of random density matrices for qubits
Lin Zhang, Jiamei Wang, Zhihua Chen
We derive the spectral density of the equiprobable mixture of two random density matrices of a two-level quantum system. We also work out the spectral density of mixture under the…
Average of uncertainty-product for bounded observables
Lin Zhang, Jiamei Wang
The goal of this paper is to calculate exactly the average of uncertainty-product of two bounded observables and to establish its typicality over the whole set of finite dimensiona…
Unified (r,s)-relative entropy
Wang Jiamei, Wu Junde
In this paper, we introduce and study unified -relative entropy and quantum unified -relative entropy, in particular, our main results of quantum unified -rela…
Entropy of Partitions on Sequential Effect Algebras
Wang Jiamei, Wu Junde, Cho Minhyung
By using the sequential effect algebra theory, we establish the partitions and refinements of quantum logics and study their entropies.
