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 …

Realizing a long coherence time quantum memory is a major challenge of current quantum
technology. Until now, the longest coherence-time of a single qubit was reported as 660 s in …

The paper proposes a cooperative scheme for the coexistence of a multiple-input-multiple-
output (MIMO) communication system and a matrix completion (MC) based, collocated …

Quantum information theory is a branch of science at the frontier of physics, mathematics,
and information science, and offers a variety of solutions that are impossible using classical …

The question of how many entangled or, respectively, separable states there are in the set of
all quantum states is considered. We propose a natural measure in the space of density …

We discuss how to generate random unitary matrices from the classical compact groups U
(N), O (N) and USp (N) with probability distributions given by the respective invariant …

The presence of uncertainty in a system description has always been a critical issue in
control. The main objective of Randomized Algorithms for Analysis and Control of Uncertain …

Universal unitary photonic devices can apply arbitrary unitary transformations to a vector of
input modes and provide a promising hardware platform for fast and energy-efficient …

We compare the entanglement of formation with a measure defined as the modulus of the
negative eigenvalue of the partial transpose. In particular we investigate whether both …

When used in quantum state estimation, projections onto mutually unbiased bases have the
ability to maximize information extraction per measurement and to minimize redundancy. We …
