Two-Color Quantum Correlation between Down-Conversion Beams at 1.5 and 3.3 μm from a Singly Resonant Optical Parametric Oscillator

open access: yesApplied Sciences, 2020
We demonstrated a two-color quantum correlation between the down-conversion beams with a telecommunication wavelength at 1.5 μm and mid-infrared wavelength at 3.3 μm generated by a singly resonant optical parametric oscillator (SRO) operated above the ...

Cosmological Spectrum of Two-Point Correlation Function from Vacuum Fluctuation of Stringy Axion Field in De Sitter Space: A Study of the Role of Quantum Entanglement

open access: yesUniverse, 2020
In this work, we study the impact of quantum entanglement on the two-point correlation function and the associated primordial power spectrum of mean square vacuum fluctuation in a bipartite quantum field theoretic system.

The Einstein–Podolsky–Rosen Steering and Its Certification

open access: yesEntropy, 2019
The Einstein–Podolsky–Rosen (EPR) steering is a subtle intermediate correlation between entanglement and Bell nonlocality. It not only theoretically completes the whole picture of non-local effects but also practically inspires novel quantum ...

Quantum-classical limit of quantum correlation functions [PDF]

open access: yesThe Journal of Chemical Physics, 2004
A quantum-classical limit of the canonical equilibrium time correlation function for a quantum system is derived. The quantum-classical limit for the dynamics is obtained for quantum systems comprising a subsystem of light particles in a bath of heavy quantum particles.

Complete condition for nonzero quantum correlation in continuous variable systems

open access: yesNew Journal of Physics, 2015
Quantum correlation provides a promising measure beyond entanglement. Here, we propose a necessary and sufficient condition for nonzero quantum correlation in continuous variable systems, which is simple and easy to perform in terms of a marker Q _r . In

Temperature Correlations of Quantum Spins [PDF]

open access: yesPhysical Review Letters, 1993
We consider isotropic XY model in the transverse magnetic field on the one dimensional lattice. Another name of the model in Heisenberg XXO model of spin 1/2.We solved long standing problem of evaluation of temperature correlations. We first represent correlation function in the model, by means of completely integrable differential equation.

Quantum discord and entanglement in grover search algorithm

open access: yesOpen Physics, 2016
Imperfections and noise in realistic quantum computers may seriously affect the accuracy of quantum algorithms. In this article we explore the impact of static imperfections on quantum entanglement as well as non-entangled quantum correlations in Grover ...

Tripartite entanglement and quantum correlation

open access: yesJournal of High Energy Physics, 2021
We provide an analytical tripartite-study from the generalized R-matrix. It provides the upper bound of the maximum violation of Mermin’s inequality. For a generic 2-qubit pure state, the concurrence or R-matrix characterizes the maximum violation of ...

Discriminating Quantum Correlations with Networking Quantum Teleportation [PDF]

open access: yesOSA Quantum 2.0 Conference, 2020
We show that quantum teleportation can be used to derive a hierarchy between the Bell nonlocality, nonbilocality, steering and nonlocality-steering hybrid correlations of processes for identifying faithful networking quantum teleportation.
