Schrödinger and Heisenberg non-Markovianity in quantum information tasks

Federico Settimo, Kimmo Luoma, Jyrki Piilo +3

Quantum non-Markovianity has been widely studied and connected to the existence of memory effects in the dynamics of open systems. Surprisingly, working in the Schrödinger or in t…

Revivals of Bell nonlocality require Schrödinger and Heisenberg non-Markovianity

Federico Settimo, Kimmo Luoma, Jyrki Piilo +3

Bell nonlocality is a key resource in quantum information, demonstrating the nonclassicality of quantum theory. Noise, however, {is in general detrimental to} nonlocality, and can…

Stochastic unravelings for Heisenberg picture and trace-nonpreserving dynamics

Federico Settimo, Kimmo Luoma, Dariusz Chruściński +3

Stochastic unravelings allow to efficiently simulate open system dynamics, yet their application has traditionally been restricted to master equations that preserve both Hermiticit…

Vibrationally Induced Resonances in Lasing

Kai Müller, Kimmo Luoma, Christian Schäfer

Optical circuits and light sources, such as lasers, undergo continuous miniaturization. In its extreme, nanolasers might be comprised of only a few molecules confined in plasmonic…

Divisibility of dynamical maps: Schrödinger vs. Heisenberg picture

Federico Settimo, Andrea Smirne, Kimmo Luoma +3

Divisibility of dynamical maps is a central notion in the study of quantum non-Markovianity, providing a natural framework to characterize memory effects via time-local master equa…

Dynamics of Open Quantum Systems with Initial System-Environment Correlations via Stochastic Unravelings

Federico Settimo, Kimmo Luoma, Dariusz Chruściński +3

In standard treatments of open quantum systems, the reduced dynamics is described starting from the assumption that the system and the environment are initially uncorrelated. This…
