This article reviews the extraordinary features of quantum information predicted by the
quantum formalism, which, combined with the development of modern quantum …

The existence of better-than-classical quantum information processing (QIP) models which
consume very little or no entanglement suggests that separable or weakly entangled states …

One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

Quantum secret sharing (QSS) has emerged as a promising avenue for storing secret with
quantum-enhanced security. However, practical applications are hindered by the challenge …

Intensive studies of entanglement properties have proven essential for our understanding of
quantum many-body systems. In contrast, much less is known about the role of quantum …

Multiparticle entanglement leads to richer correlations than two-particle entanglement and
gives rise to striking contradictions with local realism, inequivalent classes of entanglement …

In this volume, six review articles which cover a broad range of topics of current interest in
modern optics are included. The first article by S. Saltiel, AA Sukhorukov and YS Kivshar …

We invoke the black-hole–qubit correspondence to derive the classification of four-qubit
entanglement. The U-duality orbits resulting from timelike reduction of string theory from D …

Bound entanglement is central to many exciting theoretical results in quantum information
processing, but has thus far not been experimentally realized. In this work, we consider a …

We introduce a general method for the construction of quasiprobability representations for
arbitrary notions of quantum coherence. Our technique yields a non-negative probability …
