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

As light can mediate interactions between atoms in a photonic environment, engineering it
for endowing the photon-mediated Hamiltonian with desired features, like robustness …

Giant atoms, quantum emitters that couple to light at multiple discrete points, are emerging
as a new paradigm in quantum optics due to their many promising properties, such as …

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 …

In this paper, we begin with a model of a Λ-type atom whose both transitions are chirally
coupled to a wave guide and then extend the model to its giant-atom version. We investigate …

It is of fundamental interest in controlling the light–matter interaction for a long time in the
field of quantum information processing. Here, we explore a model by coupling a giant atom …

Topological insulators feature a number of topologically protected boundary modes linked to
the value of their bulk invariant. While in one-dimensional systems the boundary modes are …

We study the decay dynamics of a two-level giant atom that is coupled to a waveguide with
time-dependent coupling strengths. In the non-Markovian regime where the retardation …
