Local disclosure of quantum memory in non-Markovian dynamics

C Bäcker, K Beyer, WT Strunz - Physical Review Letters, 2024 - APS
Non-Markovian processes may arise in physics due to memory effects of environmental
degrees of freedom. For quantum non-Markovianity, it is an ongoing debate to clarify …

Non-markovian quantum dynamics in strongly coupled multimode cavities conditioned on continuous measurement

V Link, K Müller, RG Lena, K Luoma, F Damanet… - PRX Quantum, 2022 - APS
An important challenge in non-Markovian open quantum systems is to understand what
information we gain from continuous measurement of an output field. For example, atoms in …

Unraveling-paired dynamical maps recover the input of quantum channels

B Donvil, P Muratore-Ginanneschi - New Journal of Physics, 2023 - iopscience.iop.org
We explore algebraic and dynamical consequences of unraveling general time-local master
equations. We show that the'influence martingale', the paramount ingredient of a recently …

Real-time motion of open quantum systems: Structure of entanglement, renormalization group, and trajectories

EA Polyakov - Physical Review B, 2022 - APS
In this paper, we provide a complete description of the life cycle of entanglement during the
real-time motion of open quantum systems. The quantum environment can have arbitrary …

On the unraveling of open quantum dynamics

BIC Donvil, P Muratore-Ginanneschi - Open Systems & Information …, 2023 - World Scientific
It is well known that the state operator of an open quantum system can be generically
represented as the solution of a time-local equation—a quantum master equation …

[HTML][HTML] Memory effects in quantum dynamics modelled by quantum renewal processes

N Megier, M Ponzi, A Smirne, B Vacchini - Entropy, 2021 - mdpi.com
Simple, controllable models play an important role in learning how to manipulate and control
quantum resources. We focus here on quantum non-Markovianity and model the evolution …

[HTML][HTML] Measured Composite Collision Models: Quantum Trajectory Purities and Channel Divisibility

K Beyer, K Luoma, T Lenz, WT Strunz - Entropy, 2022 - mdpi.com
We investigate a composite quantum collision model with measurements on the memory
part, which effectively probe the system. The framework allows us to adjust the measurement …
