Vanishing quantum discord is not necessary for completely-positive maps
Aharon Brodutch, Animesh Datta, Kavan Modi +2
The description of the dynamics of a system that may be correlated with its environment is only meaningful within the context of a specific framework. Different frameworks rely upo…
On measures of non-Markovianity: divisibility vs. backflow of information
Dariusz Chruściński, Andrzej Kossakowski, Ángel Rivas
We analyze two recently proposed measures of non-Markovianity: one based on the concept of divisibility of the dynamical map and the other one based on distinguishability of quantu…
Stochastic resonance phenomena in spin chains
Ángel Rivas, Neil P. Oxtoby, Susana F. Huelga
We discuss stochastic resonance-like effects in the context of coupled quantum spin systems. We focus here on an information-theoretic approach and analyze the steady state quantum…
Nonclassicality of states and measurements by breaking classical bounds on statistics
Ángel Rivas, Alfredo Luis
We derive exceedingly simple practical procedures revealing the quantum nature of states and measurements by the violation of classical upper bounds on the statistics of arbitrary…
Practical schemes for the measurement of angular-momentum covariance matrices in quantum optics
Ángel Rivas, Alfredo Luis
We develop practical schemes for the measurement of the covariance matrix for intrinsic angular-momentum variables in quantum optics. We particularize this approach to two-beam pol…
Intrinsic metrological resolution as a distance measure and nonclassical light
Ángel Rivas, Alfredo Luis
We elaborate on a Hilbert-Schmidt distance measure assessing the intrinsic metrological accuracy in the detection of signals imprinted on quantum probe states by signal-dependent t…
