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…
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…
