Quantum channels and memory effects
Any physical process can be represented as a quantum channel mapping an initial state to a
final state. Hence it can be characterized from the point of view of communication theory, ie …

An invitation to quantum incompatibility
In the context of a physical theory, two devices, A and B, described by the theory are called
incompatible if the theory does not allow the existence of a third device C that would have …

Canonical form of master equations and characterization of non-Markovianity
Master equations govern the time evolution of a quantum system interacting with an
environment, and may be written in a variety of forms. Time-independent or memoryless …

Bounds on the capacity and power of quantum batteries
Quantum batteries, composed of quantum cells, are expected to outperform their classical
analogs. The origin of such advantages lies in the role of quantum correlations, which may …

Better late than never: information retrieval from black holes
We show that, in order to preserve the equivalence principle until late times in unitarily
evaporating black holes, the thermodynamic entropy of a black hole must be primarily …
