TITLE: Quantum dots in a photonic architecture


Semiconductor quantum dots are crystals so small that they behave as artificial atoms. They are excellent sources of single photons on demand, and each can serve as a qubit for quantum information technologies. Recently we have succeeded in inserting a charged quantum dot into an optical cavity formed in a photonic crystal membrane. A new fabrication technique has led to indistinguishable QDs and the demonstration of super-radiance of quantum dots in a photonic crystal waveguide. We anticipate that the quantum dot-cavity structures can ultimately serve as nodes in a quantum network connected through the emission of single photons.  I will present our current efforts in the fabrication and quantum optics measurements of individual quantum dots integrated into photonic architectures.
