Measuring quantum coherence with entanglement

A Streltsov, U Singh, HS Dhar, MN Bera, G Adesso - Physical review letters, 2015 - APS
Quantum coherence is an essential ingredient in quantum information processing and plays
a central role in emergent fields such as nanoscale thermodynamics and quantum biology …

Frozen quantum coherence

TR Bromley, M Cianciaruso, G Adesso - Physical review letters, 2015 - APS
We analyze under which dynamical conditions the coherence of an open quantum system is
totally unaffected by noise. For a single qubit, specific measures of coherence are found to …

Measures and applications of quantum correlations

G Adesso, TR Bromley… - Journal of Physics A …, 2016 - iopscience.iop.org
Quantum information theory is built upon the realisation that quantum resources like
coherence and entanglement can be exploited for novel or enhanced ways of transmitting …

Converting nonclassicality into entanglement

N Killoran, FES Steinhoff, MB Plenio - Physical review letters, 2016 - APS
Quantum mechanics exhibits a wide range of nonclassical features, of which entanglement
in multipartite systems takes a central place. In several specific settings, it is well known that …

Maximal coherence and the resource theory of purity

A Streltsov, H Kampermann, S Wölk… - New Journal of …, 2018 - iopscience.iop.org
The resource theory of quantum coherence studies the off-diagonal elements of a density
matrix in a distinguished basis, whereas the resource theory of purity studies all deviations …

Comparative investigation of the freezing phenomena for quantum correlations under nondissipative decoherence

B Aaronson, R Lo Franco, G Adesso - Physical Review A—Atomic, Molecular …, 2013 - APS
We show that the phenomenon of frozen discord, exhibited by specific classes of two-qubit
states under local nondissipative decoherent evolutions, is a common feature of all known …

Toward computability of trace distance discord

F Ciccarello, T Tufarelli, V Giovannetti - New Journal of Physics, 2014 - iopscience.iop.org
It is known that a reliable geometric quantifier of discord-like correlations can be built by
employing the so-called trace distance, which is used to measure how far the state under …

Hierarchy and dynamics of trace distance correlations

B Aaronson, RL Franco, G Compagno… - New Journal of …, 2013 - iopscience.iop.org
We define and analyze measures of correlations for bipartite states based on trace distance.
For Bell diagonal states of two qubits, in addition to the known expression for quantum …
