Verification of joint measurability using phase-space quasiprobability distributions
Saleh Rahimi-Keshari, Mohammad Mehboudi, Dario De Santis +2
Measurement incompatibility is a distinguishing property of quantum physics and an essential resource for many quantum information processing tasks. We introduce an approach to ver…

Measuring non-Markovianity via incoherent mixing with Markovian dynamics
Dario De Santis, Vittorio Giovannetti
We introduce a measure of non-Markovianity based on the minimal amount of extra Markovian noise we have to add to the process via incoherent mixing, in order to make the resulting…

Witnessing non-Markovian dynamics through correlations
Dario De Santis, Markus Johansson, Bogna Bylicka +2
Non-Markovian effects in an open-system dynamics are usually associated to information backflows from the environment to the system. However, the way these backflows manifest and h…
