Robust Entangled-Photon Ghost Imaging with Compressive Sensing
Sensors, 2019 This work experimentally demonstrates that the imaging quality of quantum ghost imaging (GI) with entangled photons can be significantly improved by properly handling the errors caused by the imperfection of optical devices.

Quantum Correlations in de Sitter Space
Universe, 2017 We study quantum correlation of a massive scalar field in a maximally entangled state in de Sitter space. We prepare two observers, one in a global chart and the other in an open chart of de Sitter space.

ARE QUANTUM CORRELATIONS GENUINELY QUANTUM? [PDF]
International Journal of Modern Physics B, 2012 It is shown that the probabilities for the spin singlet can be reproduced through classical resources, with no communication between the distant parties, by using merely shared (pseudo-)randomness. If the parties are conscious beings aware of both the hidden-variables and the random mechanism, then one has a conspiracy.

Building with quantum correlations [PDF]
Quantum Information Processing, 2010 `Correlations without correlata' is an influential way of thinking of quantum entanglement as a form primitive correlation which nonetheless maintains locality of quantum theory. A number of arguments have sought to suggest that such a view leads either to internal inconsistency or to conflict with the empirical predictions of quantum mechanics.

Correlations and How to Interpret Them
Information, 2019 Correlations between observed data are at the heart of all empirical research that strives for establishing lawful regularities. However, there are numerous ways to assess these correlations, and there are numerous ways to make sense of them.

Protecting steered coherence in squeezed generalized amplitude damping channel with memory
Results in Physics, 2023 We investigate the average steered coherence (ASC) and maximal steered coherence (MSC) of two qubits in a squeezed generalized amplitude damping channel modeled by a squeezed thermal bath with dissipation and memory. By considering the input Bell states,

Exploring multipartite quantum correlations with the square of quantum discord [PDF]
, 2013 We explore the quantum correlation distribution in multipartite quantum states based on the square of quantum discord (SQD). For tripartite quantum systems, we derive the necessary and sufficient condition for the SQD to satisfy the monogamy relation ...

Energetics of quantum correlations [PDF]
EPL (Europhysics Letters), 2009 We consider a photo--Carnot engine that consists of a single--mode radiation field in an optical cavity. One the heat reservoirs is made of a beam of thermally entangled pairs of two--level atoms that interact resonantly with the cavity. We express the thermodynamic efficiency of the engine in terms of the quantum discord of the atomic pair and find ...

Spatial quantum correlations in multiple scattered light [PDF]
, 2005 We predict a new spatial quantum correlation in light propagating through a multiple scattering random medium. The correlation depends on the quantum state of the light illuminating the medium, is infinite range, and dominates over classical mesoscopic ...

Quantum correlations and ergotropy
Physical Review E, 2022 Understanding the role of classical and quantum correlations in work extraction is a problem of fundamental importance in thermodynamics. We approach this problem by considering that, in closed quantum systems, the maximum cyclic work extractable is equal to the ergotropy.
