When is a non-Markovian quantum process classical?
More than a century after the inception of quantum theory, the question of which traits and
phenomena are fundamentally quantum remains under debate. Here, we give an answer to …

Transfer-tensor description of memory effects in open-system dynamics and multi-time statistics
The non-Markovianity of an arbitrary open quantum system is analyzed in reference to the
multi-time statistics given by its monitoring at discrete times. On the one hand, we exploit the …

Accessible coherence in open quantum system dynamics
Quantum coherence generated in a physical process can only be cast as a potentially useful
resource if its effects can be detected at a later time. Recently, the notion of non-coherence …
