Entropy of quantum states
Paolo Facchi, Giovanni Gramegna, Arturo Konderak
Given the algebra of observables of a quantum system subject to selection rules, a state can be represented by different density matrices. As a result, different von Neumann entrop…
Generic aspects of the resource theory of quantum coherence
Fabio Deelan Cunden, Paolo Facchi, Giuseppe Florio +1
The class of incoherent operations induces a pre-order on the set of quantum pure states, defined by the possibility of converting one state into the other by transformations withi…
Volume of the set of LOCC-convertible quantum states
Fabio Deelan Cunden, Paolo Facchi, Giuseppe Florio +1
The class of quantum operations known as Local Operations and Classical Communication (LOCC) induces a partial ordering on quantum states. We present the results of systematic nume…
Generalized Product Formulas and Quantum Control
Daniel Burgarth, Paolo Facchi, Giovanni Gramegna +1
We study the quantum evolution under the combined action of the exponentials of two not necessarily commuting operators. We consider the limit in which the two evolutions alternate…
