Title: "Light-matter interaction for quantum technologies"

Abstract

The coupling between light and matter bridges two different realms, taking the better parts from both worlds. It allows for an extra high degree of control of solid state excitations by an optical or a microwave field manipulation. Being observed in various solid state platforms, it brings light-matter systems to the point where useful quantum devices can be realized.
In this seminar I am going to discuss the physics of light-matter coupling using several examples.

First, I will describe semiconductor-based systems which host exciton polaritons, and introduce the area of quantum polaritonics. Second, I will concentrate on the field of microwave quantum optics and superconducting circuits, providing efficient algorithms to perform quantum simulation in this  system. Given recent experimental advances, they will enable useful quantum simulation in the nearest future.

Biography

Oleksandr Kyriienko is a Ukrainian theoretical physicist working in the fields of quantum optics and condensed matter physics.
