Exceptional point structure and chiral state transfer in a rate-operator-engineered -symmetric Bose-Hubbard dimer
Jaakko Luomala, Federico Settimo, Kimmo Luoma +2
The rate operator quantum jumps (ROQJ) is a general method to unravel a master equation describing the dynamics of an open quantum system into stochastic pure state trajectories. B…
Divisibility of Non-Invertible Quantum Dynamics in the Heisenberg Picture
Federico Settimo, Dariusz Chruściński
We study divisibility of finite-dimensional quantum dynamics in the Heisenberg picture when the dynamical maps need not be invertible. Heisenberg divisible dynamics determines uniq…
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 th…
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 ca…
Quantum jump unravelings for non-Markovian open system dynamics: a review
Federico Settimo, Jyrki Piilo
Stochastic unravelings provide a useful way to represent open quantum system dynamics in terms of pure state realizations, and have been widely studied both from a fundamental and…
Synchronization effects in a periodically driven two-level system
Federico Settimo, Bassano Vacchini
We study phase-synchronization in a driven two-level system coupled to a non-Markovian bosonic reservoir. The dynamics is described by treating the system-bath coupling and the coh…
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…
A Stochastic Schrödinger Equation for the Generalized Rate Operator Unravelings
Federico Settimo
Stochastic unravelings are a widely used tool to solve open quantum system dynamics, in which the exact solution is obtained via an average over a stochastic process on the set of…
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…
Generalized Rate Operator Quantum Jumps via Realization-Dependent Transformations
Federico Settimo, Kimmo Luoma, Dariusz Chruściński +3
The dynamics of open quantum systems is often solved by stochastic unravellings where the average over the state vector realizations reproduces the density matrix evolution. We foc…
