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 …

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 …

We study the generation of quantum entanglement between two giant atoms coupled to a
one-dimensional waveguide. Since each giant atom interacts with the waveguide at two …

In quantum optics, it is common to assume that atoms are pointlike objects compared to the
wavelength of the electromagnetic field they interact with. However, this dipole …

We study chiral and nonreciprocal single-photon scattering in a chiral-giant-molecule
waveguide-QED system. Here, the giant molecule consists of two coupled giant atoms …

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 …

Giant atoms provide a promising platform for engineering decoherence-free interactions,
which is a major task in modern quantum technologies. Here we study systematically how to …

We study the disentanglement dynamics of two giant atoms coupled to a common one-
dimensional waveguide. We focus on the non-Markovian retarded effect in the …

Giant atoms are a new paradigm of quantum optics going beyond the usual local coupling.
Building on this, a new type of decoherence-free (DF) many-body Hamiltonians was shown …

Giant artificial atoms are promising and flexible building blocks for the implementation of
analog quantum simulators. They are realized via a multilocal pattern of couplings of two …
