In recent years, quantum collision models, sometimes dubbed repeated interaction models,
have gained much attention due to their simplicity and their capacity to convey ideas without …

The field of classical stochastic processes forms a major branch of mathematics. Stochastic
processes are, of course, also very well studied in biology, chemistry, ecology, geology …

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 …

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

Quantum computers present a compelling platform for the study of open quantum systems,
namely, the nonunitary dynamics of a system. Here, we investigate and report digital …

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 …

We study the performance of a quantum Otto cycle using a harmonic work medium and
undergoing collisional dynamics with finite-size reservoirs. We span the dynamical regimes …

We formally extend the notion of Markov order to open quantum processes by accounting for
the instruments used to probe the system of interest at different times. Our description …

Non-Markovian quantum processes exhibit different memory effects when measured in
different ways; an unambiguous characterization of memory length requires accounting for …
