Event Information:

As the various quantum photonic platforms mature, we rapidly approach the advent of viable quantum devices.  The different ways in which we can manipulate and create quantum states, and how efficiently we can do so, will determine the types of devices that we can realistically construct.  In this talk, I will cover our recent progress on the control of the properties of epitaxially grown InAs quantum dots embedded in GaAs nanophotonic waveguides, and over their interaction with photons.  I will touch on the high quality of these interactions, and their nonlinear and directional nature, showing that this combination can be used to create a viable photon sorter, and even a bell-state analyzer. I will also cover the manner in which these interactions can be actively and optically controlled by exploiting the inherent nonlinearity of a two-level quantum emitter. In total, these results demonstrate a route towards future quantum technologies, ranging from the creation of single-photon sources to the realization of large-scale quantum networks.
