Vapor phase epitaxially-grown and solution-grown colloidal semiconductor nanocrystal quantum nanostructures constitute the two dominant classes of quantum dots. The former derives from, and thus is naturally integrable with, the highly developed electronics and optoelectronics technologies for information processing and communication. The latter, largely owing to its flexibility, richness, and lower cost of synthesis, has been under study as an alternative approach for certain applications such as solar energy conversion and environmental hazard sensing but its compatibility with liquid environment is a particular strength that makes it unique for use in diagnostic and therapeutic medical technologies as well.

 After a brief introduction to the basic physics, fabrication, and characterization of quantum dots, I will focus on colloidal nanocrystal quantum dots and their applications in Talk I. In Talk II, I will focus on the fundamental physics of single photon emitters, the current status of realizing their spectrally uniform spatially regular arrays of single quantum based dot single photon emitters essential for optical quantum information processing platforms, and their potential on-chip integration with essential passive elements (such as waveguides, beam splitters, etc.) to create nanophotonic optical circuits that lend themselves to extension to single photon quantum optical circuits.
