"Quantum Optics in Photonic Crystals: Applications to Classical and Quantum Information Processing"
Nanoscale optical structures open a way to control the interaction of photons with single emitters in solids, such as semiconductor quantum dots or color centers. In this talk, I will describe how this controlled light matter interaction can be used to construct basic components for quantum information science, a field that exploits inherently quantum mechanical effects to process and exchange information in ways that cannot be achieved classically. I will describe cavity-enhanced generation of single photons; nonlinear optical interactions at the single photon level; and nonclassical state generation by photon blockade and tunneling.
The ability to control the interaction between single emitters and single photons also opens exciting opportunities for a new generation of devices at the intersection of quantum and classical information processing. Such `quantum photonic' devices could enable high-speed signal processing at the few-photon level and low-power electro-optical switching in optical interconnects.
