Query: Measuring and using non-markovianity   We construct measures for the non-Markovianity of quantum evolution with a
physically meaningful interpretation. We first provide a general setting in the
framework of channel capacities and propose two families of meaningful
quantitative measures, based on the largest revival of a channel capacity,
avoiding some drawbacks of other non-Markovianity measures. We relate the
proposed measures to the task of information screening. This shows that the
non-Markovianity of a quantum process may be used as a resource. Under these
considerations, we analyze two paradigmatic examples, a qubit in a quantum
environment with classically mixed dynamics and the Jaynes-Cummings model.
