Quantum Nanophotonics

Course 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
