This book reviews progress towards quantum simulators based on photonic and hybrid light-matter systems, covering theoretical proposals and recent experimental work. Quantum simulators are specially designed quantum computers. Their main aim is to simulate and understand complex and inaccessible quantum many-body phenomena found or predicted in condensed matter physics, materials science and exotic quantum field theories. Applications will include the engineering of smart materials, robust optical or electronic circuits, deciphering quantum chemistry and even the design of drugs.

Technological developments in the fields of interfacing light and matter, especially in many-body quantum optics, have motivated recent proposals for quantum simulators based on strongly correlated photons and polaritons generated in hybrid light-matter systems. The latter have complementary strengths to cold atom and ion based simulators and they can probe for example out of equilibrium phenomena in a natural driven-dissipative setting. This book covers some of the most important works in this area reviewing the proposal for Mott transitions and Luttinger liquid physics with light, to simulating interacting relativistic theories, topological insulators and gauge field physics. The stage of the field now is at a point where on top of the numerous theory proposals; experiments are also reported.

Connecting to the theory proposals presented in the chapters, the main experimental quantum technology platforms developed from groups worldwide to realize photonic and polaritonic simulators in the laboratory are also discussed. These include coupled microwave resonator arrays in superconducting circuits, semiconductor based polariton systems, and integrated quantum photonic chips. This is the first book dedicated to photonic approaches to quantum simulation, reviewing the fundamentals for the researcher new to the field, and providing a complete reference for the graduate student starting or already undergoing PhD studies in this area.

The first title to address the growing field of photonic quantum simulators Contains contributions from all leading groups working in the field reviewing many different approaches Describes theoretical proposals and ongoing experimental work Includes supplementary material: sn.pub/extras

Autorentext
Dimitris G. Angelakis works in the interface of quantum optics, condensed matter physics, and quantum computation, and more specifically the area of Quantum Simulators, which is understanding and predicting (simulating) the behaviour of matter. His main focus is photonic quantum simulators, an area he co-founded a few years ago, where crystals made of photons mimick the behaviour of crystals made of atoms and electrons. He employs hybrid light-matter systems were the strong light matter interaction allows for engineering photonic states that could simulate (mimick) quantum many body effects found in condensed matter systems.
