In this project we aim to develop analog quantum simulation platforms to emulate quantum impurity models in the ultra-strong coupling regime [1] and complex spin-spin Hamiltonians using atom-photon

Emergence of solitons from many-body photon bound states in quantum nonlinear media

Solitons are known to occur in the context of atom-light interaction via the well-known semi-classical phenomenon of self-induced transparency (SIT). Separately, in the regime where both light and

Bound state in a giant atom-modulated resonators system

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 with the

Topological Entanglement Stabilization in Superconducting Quantum Circuits

Topological properties of quantum systems are one of the most intriguing emerging phenomena in condensed matter physics. A crucial property of topological systems is the symmetry-protected robustness

Interaction between giant atoms in a one-dimensional structured environment

Giant atoms—quantum emitters that couple to light at multiple discrete points—are emerging as a new paradigm in quantum optics thanks to their many promising properties, such as decoherence-free

Quantum Electrodynamics in a Topological Waveguide

While designing the energy-momentum relation of photons is key to many linear, non-linear, and quantum optical phenomena, a new set of light-matter properties may be realized by employing the

Universal quantum computation in waveguide QED using decoherence free subspaces

The interaction of quantum emitters with one-dimensional photon-like reservoirs induces strong and long-range dissipative couplings that give rise to the emergence of the so-called decoherence free

Beyond strong coupling in a multimode cavity

The study of light-matter interaction has seen a resurgence in recent years, stimulated by highly controllable, precise, and modular experiments in cavity quantum electrodynamics (QED). The

Ultrastrong coupling dynamics with a transmon qubit

The interaction of light and matter is often described by the exchange of single excitations. When the coupling strength is a significant fraction of the system frequencies, the number of excitations

Charge-insensitive qubit design derived from the Cooper pair box

Short dephasing times pose one of the main challenges in realizing a quantum computer. Different approaches have been devised to cure this problem for superconducting qubits, a prime example being

Collapse and Revival of an Artificial Atom Coupled to a Structured Photonic Reservoir

A structured electromagnetic reservoir can result in novel dynamics of quantum emitters. In particular, the reservoir can be tailored to have a memory of past interactions with emitters, in contrast

Quantum simulations and many-body physics with light

This review discusses the works in the area of quantum simulation and many-body physics with light, from the early proposals on equilibrium models to the more recent works in driven dissipative platforms and some of the relatively recent results predicting exotic phases such as super-solidity and Majorana like modes.

Resonant atom-field interaction in large-size coupled-cavity arrays

We consider an array of coupled cavities with staggered intercavity couplings, where each cavity mode interacts with an atom. In contrast to large-size arrays with uniform hopping rates where the

Supercorrelated Radiance in Nonlinear Photonic Waveguides.

An effective Markovian theory is derived to model the resulting decay dynamics of an arbitrary distribution of emitters and identify collective effects beyond the usual phenomena of super- and subradiance in the limit of many close-by emitters.

Universal photonic quantum computation via time-delayed feedback

It is shown that in state-of-the-art experiments with single atom-like quantum emitters, the most basic form of delayed quantum feedback already allows for creation of states that are universal resources for quantum computation, which opens avenues for quantum information processing with photons using minimal experimental resources.
