On conjectures of classical and quantum correlations in bipartite states
In this paper, two conjectures which were proposed in Luo et al (2010 Phys. Rev. A http://dx.doi.org/10.1103/PhysRevA.82.052122) on the correlations in a bipartite state ρAB are studied. If the…

Antosik-Mikusinski Matrix Convergence Theorem in Quantum Logics
In this paper we establish the order topology type Antosik-Mikusinski infinite matrix convergence theorem in quantum logics. As application, we prove the Hahn-Schur summation theorem in quantum…

We define two ways of quantifying the quantum correlations based on quantum Fisher information (QFI) in order to study the quantum correlations as a resource in quantum metrology. By investigating…

Quantum noise is ubiquitous to quantum systems as they incessantly interact with their surroundings and results in degrading useful resources such as coherence for single quantum systems and quantum…

In this paper, we present a general framework to solve a fundamental problem in Random Matrix Theory (RMT), i.e., the problem of describing the joint distribution of eigenvalues of the sum…
Tomita-Takesaki Modular Theory vs. Quantum Information Theory
In this paper, we will try to find out the relationship between separating and cyclic vectors in the theory of von Neumann algebra and entangled states in the theory of quantum information. The…
