Hybrid no-signaling-quantum correlations
New Journal of Physics, 2022 Fundamental investigations in non-locality have shown that while the no-signaling principle alone is not sufficient to single out the set of quantum non-local correlations, local quantum mechanics and no-signaling together exactly reproduce the set of ...

Interplays between classical and quantum entanglement-assisted communication scenarios
New Journal of Physics, 2023 Prepare-and-measure scenarios ( pm ), in their many forms, can be seen as the basic building blocks of communication tasks. As such, they can be used to analyze a diversity of classical and quantum protocols—of which dense coding and random access codes ...

Quantum correlations in optomechanical crystals [PDF]
Physical Review A, 2019 The field of optomechanics provides us with several examples of quantum photon-phonon interface. In this paper, we theoretically investigate the generation and manipulation of quantum correlations in a microfabricated optomechanical array.

Are quantum correlations symmetric?
Quantum Information and Computation, 2010 We provide operational definition of asymmetry of entanglement: An entangled state contains asymmetric entanglement if its subsystems can not be exchanged (swapped) by means of local operations and classical communication. We show that in general states have asymmetric entanglement.

The power of qutrits for non-adaptive measurement-based quantum computing
New Journal of Physics, 2023 Non-locality is not only one of the most prominent quantum features but can also serve as a resource for various information-theoretical tasks. Analysing it from an information-theoretical perspective has linked it to applications such as non-adaptive ...

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 ...

Quantum correlations in separable multi-mode states and in classically entangled light [PDF]
Reports on progress in physics. Physical Society, 2019 In this review we discuss intriguing properties of apparently classical optical fields, that go beyond purely classical context and allow us to speak about quantum characteristics of such fields and about their applications in quantum technologies.

Bounding quantum correlations with indefinite causal order
New Journal of Physics, 2015 Causal inequalities are bounds on correlations obtained when operations take place in a causal sequence, i.e. in which the background time or definite causal structure pre-exists such that every operation is either in the future, in the past or space ...

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.
