Nonlinear quantum optics: theory, engineering, and applications

Tuesday January 30, 2018
3:30 pm

 Presenter:  Joshua Combes, University of Queensland
 Series:  CQuIC Seminars
 Abstract:  Recent advances in experimental nonlinear quantum optics, at the single photon and single atom level, motivate the development of new theoretical frameworks and applications. In this talk, I will show that it is possible to engineer interactions between photons so that one can build a deterministic optical quantum computer, solving a ten year old problem in quantum optics. Then I will discuss the development of a formalism that enables one to examine properties of the light-matter interaction in the deep quantum regime. This formalism broadly applicable, e.g. it has been used to design single-photon detectors at microwave frequencies. Finally, I will show how experimentally accessible nonlinearities can motivate the development of a new class of continuous-variable quantum error correcting codes.
