Content
Quantum optics in solid-state nanophotonics systems is a rapidly progressing research field that focuses on controlling the interaction between light and matter.

The course will provide an introduction to the quantum optical description of light-matter interaction in nanophotonic structures. The physics of dielectric nanophotonics structures will be discussed in details including photonic crystal cavities and waveguides. Furthermore, the optical properties of solid-state light emitters (quantum dots) are introduced. The interaction between photons and quantum dots provides the core of the course including the discussion of Wigner-Weisskopf theory of spontaneous emission in nanostructures, the master equation description of light-matter interaction with dephasing, and cavity quantum electrodynamics. In the later part of the course examples of modern research topics will be discussed including also experimental aspects of highly-efficient single-photon sources and basic quantum information.

Aim and content
Quantum optics in solid-state nanophotonic systems is a rapidly progressing research field that focuses on controlling the interaction between light and matter. This opens whole new opportunities for generating entanglement and other quantum resources in a scalable solid-state platform that may lead to practical implementations of quantum-information processing.

The course will provide an introduction to the quantum description of light-matter interaction in nanophotonics. The underlying physics of nanophotonics structures will be introduced in details including photonic-crystal cavities and waveguides. Furthermore, the optical properties of solid-state light emitters (quantum dots) are introduced. The interaction between photons and quantum dots provides the core of the course including the discussion of Wigner-Weisskopf theory of spontaneous emission in nanostructures, the master equation description of light-matter interaction with dephasing, and cavity quantum electrodynamics. This material will form the basis for understanding modern research topics that are considered in the later part of the course including deterministic single-photon sources and giant single-photon nonlinearities, and their applications in quantum-information processing

Learning outcome
The aim of the course is to bring the students at a level where they are capable of comprehending modern research literature on quantum nanophotonics.

Specifically, after following this course students should be able to:

Skills:
discuss the concept of dephasing and the consequences for light emission
analyze the different quantum electrodynamics regimes for a quantum emitter in a cavity
discuss methods of creating an efficient single-photon source and the applications of it
discuss basic quantum information protocols implemented in solid-state systems

Knowledge:
describe basic principles of photonic crystals
explain the concepts of photonic crystal cavities and waveguides
explain fundamental principles of light emission from quantum dots
account for the theory of spontaneous emission in photonic nanostructures

Competences:
This course will provide the students with a competent background for doing research within solid-state quantum optics, i.e. through a M.Sc. project.

Teaching and learning methods
Lectures and Exercises.

Remarks
