Sensors, 2022 A quantum illumination radar uses quantum entanglement to enhance photodetection sensitivity. The entanglement is quickly destroyed by the decoherence in an environment, although the sensitivity enhancement could survive thanks to quantum correlations ...

A synchronous game for binary constraint systems
, 2017 Recently, W. Slofstra proved that the set of quantum correlations is not closed. We prove that the set of synchronous quantum correlations is not closed, which implies his result, by giving an example of a synchronous game that has a perfect quantum ...

The exclusivity principle forbids sets of correlations larger than the quantum set [PDF]
, 2013 We show that the exclusivity (E) principle singles out the set of quantum correlations associated to any exclusivity graph assuming the set of quantum correlations for the complementary graph. Moreover, we prove that, for self-complementary graphs, the E

Equilibrium and nonequilibrium quantum correlations between two detectors in curved spacetime
European Physical Journal C: Particles and Fields, 2022 We investigate the equilibrium and nonequilibrium quantum information correlations encoded in a two-qubit system in curved spacetime near the horizon of a Kerr black hole.

Correlations in optically-controlled quantum emitters
, 2012 We address the problem of optically controlling and quantifying the dissipative dynamics of quantum and classical correlations in a set-up of individual quantum emitters under external laser excitation. We show that both types of correlations, the former

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Beating one bit of communication with and without quantum pseudo-telepathy
npj Quantum InformationAccording to Bell’s theorem, certain entangled states cannot be simulated classically using local hidden variables (LHV). Suppose that we can augment LHV by some amount of classical communication.

Simulating extremal temporal correlations
New Journal of Physics, 2020 The correlations arising from sequential measurements on a single quantum system form a polytope. This is defined by the arrow-of-time (AoT) constraints, meaning that future choices of measurement settings cannot influence past outcomes.

Correlations for computation and computation for correlations
npj Quantum Information, 2021 Quantum correlations are central to the foundations of quantum physics and form the basis of quantum technologies. Here, our goal is to connect quantum correlations and computation: using quantum correlations as a resource for computation—and vice versa,

Verifying the Quantumness of Bipartite Correlations [PDF]
Physical Review Letters, 2016 Entanglement is at the heart of most quantum information tasks, and therefore considerable effort has been made to find methods of deciding the entanglement content of a given bipartite quantum state. Here, we prove a fundamental limitation to deciding if an unknown state is entangled or not: we show that any quantum measurement which can answer this ...
