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 …

The dynamical behavior of open quantum systems plays a key role in many applications of
quantum mechanics, examples ranging from fundamental problems, such as the …

We introduce the multipartite collision model, defined in terms of elementary interactions
between subsystems and ancillas, and show that it can simulate the Markovian dynamics of …

Understanding and simulating how a quantum system interacts and exchanges information
or energy with its surroundings is a ubiquitous problem, one which must be carefully …

In the classical domain, it is well known that divisibility does not imply that a stochastic
process is Markovian. However, for quantum processes, divisibility is often considered to be …

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

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 …

The divisibility of dynamical maps is visualized by trajectories in the parameter space and
analyzed within the framework of collision models. We introduce ultimate completely positive …

Non-Markovianity has recently attracted large interest due to significant advances in its
characterization and its exploitation for quantum information processing. However, up to …

The effective description of the weak interaction between an emitter and a bosonic field as a
sequence of two-body collisions provides a simple intuitive picture compared to traditional …
