Signature of non-Markovianity in continuous-variable quantum systems

Gianpaolo Torre

Department of Physics, Faculty of Science, University of Zagreb, Zagreb

Usually, the dynamics of open quantum systems is modelled through
Markovian processes, in which the open system continuously loses
information to its surroundings. However, despite the enormous success
of
the Markovian approximation, the interest in non-Markovian processes is
exponentially growing. Indeed, on one hand, it is not always possible to
rely
on simplifying assumptions such as weak coupling and factorization of
the
initial system-environment state. On the other, non-Markovianity can be
exploited as a resource for quantum information tasks. After reviewing
these concepts I discuss the problem of characterizing non-Markovianity
for
continuous-variable quantum systems. In particular, I present a reliable
measure of non-Markovianity for quantum Gaussian channels. Moreover, I
discuss its properties and its possible applications to quantum
information
science.

Cjeloviti oglas je u prilogu./Formatted announcement is attached.

Lijep pozdrav / Best regards
