Quantum Reactivity: An Indicator of Quantum Correlation [PDF]

Entropy, 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 ...

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.

Bounding the Set of Quantum Correlations [PDF]

Physical Review Letters, 2007
We introduce a hierarchy of conditions necessarily satisfied by any distribution P(ab) representing the probabilities for two separate observers to obtain outcomes a and b when making local measurements on a shared quantum state. Each condition in this hierarchy is formulated as a semidefinite program. Our approach can be used to obtain upper-bounds on

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.

Converting Coherence to Quantum Correlations [PDF]

Physical Review Letters, 2016
Recent results in quantum information theory characterize quantum coherence in the context of resource theories. Here we study the relation between quantum coherence and quantum discord, a kind of quantum correlation which appears even in non-entangled states.
