Experimental quantification of spatial correlations in quantum dynamics [PDF]

open access: yesQuantum, 2018
Correlations between different partitions of quantum systems play a central role in a variety of many-body quantum systems, and they have been studied exhaustively in experimental and theoretical research.

Almost Quantum Correlations are Inconsistent with Specker's Principle [PDF]

open access: yesQuantum, 2017
Ernst Specker considered a particular feature of quantum theory to be especially fundamental, namely that pairwise joint measurability of sharp measurements implies their global joint measurability (vimeo.com/52923835).

Quantum Reactivity: An Indicator of Quantum Correlation [PDF]

open access: yesEntropy, 2019
Geometry is often a valuable guide to complex problems in physics. In this paper, we introduce a novel geometric quantity called quantum reactivity (QR) to probe quantum correlations in higher-dimensional quantum systems. Much like quantum discord, QR is not a measure of quantum entanglement but can be useful in quantum information processes where a ...

Advanced quantum noise correlations

open access: yesNew Journal of Physics, 2014
We use the quantum correlations of twin beams of light to investigate the fundamental addition of noise when one of the beams propagates through a fast-light medium based on phase-insensitive gain.

Quantum correlations for anonymous metrology [PDF]

open access: yesQuantum, 2019
We introduce the task of anonymous metrology, in which a physical parameter of an object may be determined without revealing the object's location. Alice and Bob share a correlated quantum state, with which one of them probes the object.

Correlations in Two-Qubit Systems under Non-Dissipative Decoherence

open access: yesAxioms, 2020
We built a new set of suitable measures of correlations for bipartite quantum states based upon a recently introduced theoretical framework [Bussandri et al. in Quantum Inf. Proc. 18:57, 2019].

Extremal quantum correlation generation using a hybrid channel

open access: yesScientific Reports, 2023
The preservation of quantum correlations requires optimal procedures and the proper design of the transmitting channels. In this regard, we address designing a hybrid channel comprising a single-mode cavity accompanied by a super-Gaussian beam and local ...
