All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Quantum correlations between two parties are essential for the argument of Einstein,
Podolsky, and Rosen in favor of the incompleteness of quantum mechanics. Schrödinger …

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 …

Entanglement is a quintessential quantum mechanical phenomenon with no classical
equivalent. First discussed by Einstein, Podolsky, and Rosen and formally introduced by …

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 …

Communication over a noisy quantum channel introduces errors in the transmission that
must be corrected. A fundamental bound on quantum error correction is the quantum …

We review the criteria for separability and quantum entanglement, both in a bipartite as well
as a multipartite setting. We discuss Bell inequalities, entanglement witnesses, entropic …

Secret sharing is a conventional technique for realizing secure communications in
information networks, where a dealer distributes to n players a secret, which can only be …

Quantum entanglement is a key physical resource in quantum information processing that
allows for performing basic quantum tasks such as teleportation and quantum key …

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