Quantum Nonlocality in Any Forked Tree-Shaped Network
Entropy, 2022 In the last decade, much attention has been focused on examining the nonlocality of various quantum networks, which are fundamental for long-distance quantum communications.

Journal of the European Optical Society-Rapid Publications, 2023 We investigate the atom-field system in the framework of harmonic oscillators based on deformed Heisenberg algebras. We explore the dynamic characteristics of the considered system under the effect of a nonlinear field.

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.

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,

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.

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.

Stronger-Than-Quantum Correlations [PDF]
Foundations of Physics, 1998 After an elementary derivation of Bell's inequality, several forms of expectation functions for two-valued observables are discussed. Special emphasis is given to hypothetical stronger-than quantum expectation functions which give rise to a maximal violation of Bell's inequality.

Correlated Markov Quantum Walks [PDF]
Annales Henri Poincaré, 2012 We consider the discrete time unitary dynamics given by a quantum walk on $\Z^d$ performed by a particle with internal degree of freedom, called coin state, according to the following iterated rule: a unitary update of the coin state takes place, followed by a shift on the lattice, conditioned on the coin state of the particle.

Universal optimal quantum correlator [PDF]
International Journal of Quantum Information, 2014 Recently, a novel operational strategy to access quantum correlation functions of the form Tr[AρB] was provided in [F. Buscemi, M. Dall'Arno, M. Ozawa and V. Vedral, arXiv:1312.4240]. Here we propose a realization scheme, that we call partial expectation values, implementing such strategy in terms of a unitary interaction with an ancillary system ...
