Quantum collision models: Open system dynamics from repeated interactions

F Ciccarello, S Lorenzo, V Giovannetti, GM Palma - Physics Reports, 2022 - Elsevier
We present an extensive introduction to quantum collision models (CMs), also known as
repeated interactions schemes: a class of microscopic system–bath models for investigating …

Collision models in quantum optics

F Ciccarello - Quantum Measurements and Quantum Metrology, 2017 - degruyter.com
Quantum collision models (CMs) provide advantageous case studies for investigating major
issues in open quantum systems theory, and especially quantum non-Markovianity. After …

System-environment correlations and Markovian embedding of quantum non-Markovian dynamics

S Campbell, F Ciccarello, GM Palma, B Vacchini - Physical Review A, 2018 - APS
We study the dynamics of a quantum system whose interaction with an environment is
described by a collision model, ie, the open dynamics is modeled through sequences of …

Battery charging in collision models with Bayesian risk strategies

GT Landi - Entropy, 2021 - mdpi.com
We constructed a collision model where measurements in the system, together with a
Bayesian decision rule, are used to classify the incoming ancillas as having either high or …

Simulation of open-quantum-system dynamics using the quantum Zeno effect

S Patsch, S Maniscalco, CP Koch - Physical Review Research, 2020 - APS
We suggest a quantum simulator that allows to study the role of memory effects in the
dynamics of open quantum systems. A particular feature of our simulator is the ability to …

Non-Markovianity in the collision model with environmental block

J **, C Yu - New Journal of Physics, 2018 - iopscience.iop.org
We present an extended collision model to simulate the dynamics of an open quantum
system. In our model, the unit to represent the environment is, instead of a single particle, a …

Memory kernel and divisibility of Gaussian collisional models

RR Camasca, GT Landi - Physical Review A, 2021 - APS
Memory effects in the dynamics of open systems have been the subject of significant interest
in the last decades. The methods involved in quantifying this effect, however, are often …

Steady-state quantum transport through an anharmonic oscillator strongly coupled to two heat reservoirs

T Chen, V Balachandran, C Guo, D Poletti - Physical Review E, 2020 - APS
We investigate the transport properties of an anharmonic oscillator, modeled by a single-site
Bose-Hubbard model, coupled to two different thermal baths using the numerically exact …

Correlations breaking homogenization

NE Comar, GT Landi - Physical Review A, 2021 - APS
The standard collisional model paradigm consists of a system that interacts sequentially with
identically prepared ancillas. After infinitely many collisions, and under appropriate …

Information scrambling in a collision model

Y Li, X Li, J ** - Physical Review A, 2020 - APS
The information scrambling in many-body systems is closely related to quantum chaotic
dynamics, complexity, and gravity. Here we propose a collision model to simulate the …
