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…
Entanglement and quantum correlations in many-body systems: a unified approach via local unitary operations
M. Cianciaruso, S. M. Giampaolo, W. Roga +3
Local unitary operations allow for a unifying approach to the quantification of quantum correlations among the constituents of a bipartite quantum system. For pure states, the dist…
Universal freezing of quantum correlations within the geometric approach
Marco Cianciaruso, Thomas R. Bromley, Wojciech Roga +2
Quantum correlations in a composite system can be measured by resorting to a geometric approach, according to which the distance from the state of the system to a suitable set of c…
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…
