An introduction to quantum discord and non-classical correlations beyond entanglement
Gerardo Adesso, Marco Cianciaruso, Thomas R. Bromley
In this didactic article we explore the concept of quantum correlations beyond entanglement. We begin by introducing and motivating the classically correlated states and then showi…
Frozen Quantum Coherence
Thomas R. Bromley, Marco Cianciaruso, Gerardo Adesso
We analyse 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…
Classical nature of ordered phases: origin of spontaneous symmetry breaking
M. Cianciaruso, L. Ferro, S. M. Giampaolo +2
We investigate the nature of spontaneous symmetry breaking in complex quantum systems by conjecturing that the maximally symmetry breaking quantum ground states are the most classi…
Unifying approach to the quantification of bipartite correlations by Bures distance
Thomas R. Bromley, Marco Cianciaruso, Rosario Lo Franco +1
The notion of distance defined on the set of states of a composite quantum system can be used to quantify total, quantum and classical correlations in a unifying way. We provide ne…
