We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

In spite of many results in quantum information theory, the complex nature of compound
systems is far from clear. In general the information is a mixture of local and nonlocal …

Quantum nonlocality is usually associated with entangled states by their violations of Bell-
type inequalities. However, even unentangled systems, whose parts may have been …

It is well known that orthogonal quantum states can be distinguished perfectly. However, if
we assume that these orthogonal quantum states are shared by spatially separated parties …

We explicitly exhibit a set of four ququad-ququad orthogonal maximally entangled states that
cannot be perfectly distinguished by means of local operations and classical …

In 2⊗ 2, more than two orthogonal Bell states with a single copy can never be discriminated
with certainty if only local operations and classical communication (LOCC) are allowed. We …

Two types of results are presented for distinguishing pure bipartite quantum states using
local operations and classical communications. We examine sets of states that can be …

We show that entanglement guarantees difficulty in the discrimination of orthogonal
multipartite states locally. The number of pure states that can be discriminated by local …

We study the local indistinguishability of mutually orthogonal product basis quantum states
in the high-dimensional quantum system. In the quantum system of C d⊗ C d, where d is …

In this paper, we mainly study the local indistinguishability of mutually orthogonal product
basis quantum states in the high-dimensional quantum systems. In the Hilbert space of 3⊗ 3 …
