Linear and nonlinear photonic quantum circuits

Nir Rotenberg

Quantum Nanophotonics Lab at Queen’s University in Canada

Abstract: Self-assembled quantum dots in nanophotonic structures are a wonderful platform for the exploration of fundamental physics and for quantum photonic technologies. Fundamentally, they allow for the controlled exploration of few-body effects and few-photon nonlinearities, while from a technical perspective they act as on-demand sources of single or entangled photons, all because of the high quality of both these emitters and the structures into which they are embedded. Recently, at Queen’s University, we have began exploring other ways in which these properties could be used to realize quantum technologies, focusing on quantum photonic circuits. In this talk, I will discuss these efforts, covering what is possible if the circuits are fully linear or if nonlinearities are available, and highlighting roles that quantum dots may play.

Bio: Dr. Rotenberg leads the Quantum Nanophotonics Lab at Queen’s University in Canada, where he has been since mid 2020. The groups research focuses on controlling and exploiting light-matter interactions with quantum dots embedded on photonic chips. This continues a research direction from his time at the Niels Bohr Institute, before which he studied quantum optics with single organic molecules as a postdoc at the Max Planck Institute for the Science of Light in Germany.
