The Differential Entropy of the Joint Distribution of Eigenvalues of Random Density Matrices
Entropy, 2016 We derive exactly the differential entropy of the joint distribution of eigenvalues of Wishart matrices. Based on this result, we calculate the differential entropy of the joint distribution of eigenvalues of random mixed quantum states, which is induced

Extremal quantum correlation generation using a hybrid channel
Scientific Reports, 2023 The preservation of quantum correlations requires optimal procedures and the proper design of the transmitting channels. In this regard, we address designing a hybrid channel comprising a single-mode cavity accompanied by a super-Gaussian beam and local ...

A Note on Complexities by Means of Quantum Compound Systems
Entropy, 2020 It has been shown that joint probability distributions of quantum systems generally do not exist, and the key to solving this concern is the compound state invented by Ohya.

Caputo Fractional Derivative and Quantum-Like Coherence
Entropy, 2021 We study two forms of anomalous diffusion, one equivalent to replacing the ordinary time derivative of the standard diffusion equation with the Caputo fractional derivative, and the other equivalent to replacing the time independent diffusion coefficient

Quantum properties of classical Fisher information [PDF]
, 1999 The Fisher information of a quantum observable is shown to be proportional to both (i) the difference of a quantum and a classical variance, thus providing a measure of nonclassicality; and (ii) the rate of entropy increase under Gaussian diffusion, thus

Measuring Arbitrary Physical Properties in Analog Quantum Simulation
Physical Review X, 2023 A central challenge in analog quantum simulation is to characterize desirable physical properties of quantum states produced in experiments. However, in conventional approaches, the extraction of arbitrary information requires performing measurements in ...

Introduction to Quantum Logical Information Theory: Talk
EPJ Web of Conferences, 2018 Logical information theory is the quantitative version of the logic of partitions just as logical probability theory is the quantitative version of the dual Boolean logic of subsets. The resulting notion of information is about distinctions, differences,

Randomness, Nonlocality and information in entagled correlations [PDF]
, 1995 It is shown that the Einstein, Podolsky and Rosen (EPR) correlations for arbitrary spin-s and the Greenberger, Horne and Zeilinger (GHZ) correlations for three particles can be described by nonlocal joint and conditional quantum probabilities.

Alternative fidelity measure for quantum states [PDF]
, 2008 We propose an alternative fidelity measure (namely, a measure of the degree of similarity) between quantum states and benchmark it against a number of properties of the standard Uhlmann-Jozsa fidelity.
