In many applications entanglement must be distributed through noisy communication
channels that unavoidably degrade it. Entanglement cannot be generated by local …

We study the dynamics of a spin-1/2 particle interacting with a multi-spin environment,
modelling the corresponding open system dynamics through a collision-based model. The …

Controlling the non-Markovian dynamics of open quantum systems is essential in quantum
information technology since it plays a crucial role in preserving quantum memory. Albeit in …

We show that complete positivity is not only sufficient but also necessary for the validity of
the quantum data-processing inequality. As a consequence, the reduced dynamics of a …

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 …
