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 ...

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.

Genuine quantum correlations in quantum many-body systems: a review of recent progress [PDF]
Reports on progress in physics. Physical Society, 2017 Quantum information theory has considerably helped in the understanding of quantum many-body systems. The role of quantum correlations and in particular, bipartite entanglement, has become crucial to characterise, classify and simulate quantum many body ...

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 ...

Emergence of quantum correlations from interacting fibre-cavity polaritons [PDF]
Nature Materials, 2017 Over the past decade, exciton-polaritons in semiconductor microcavities have revealed themselves as one of the richest realizations of a light-based quantum fluid1, subject to fascinating new physics and potential applications2–6.

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.

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 ...

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 ...

Non-closure of the Set of Quantum Correlations via Graphs [PDF]
Communications in Mathematical Physics, 2017 We prove that the set of quantum correlations for a bipartite system of 5 inputs and 2 outputs is not closed. Our proof relies on computing the correlation functions of a graph, which is a concept that we introduce.
