Kevin Silverman: Epitaxial Quantum Dots for Single Photonics and Opto-Mechanics

Abstract: Epitaxial semiconductor quantum dots (QDs) are promising sources of single photons for optical quantum computing and quantum networks. Recent advances in photon purity and collection efficiency have poised them to challenge spontaneous parametric down-conversion (SPDC) sources for deployment in next-generation quantum information architectures. In addition, QDs interact strongly with other quantum systems enabling hybrid architectures exhibiting the ‘best’ properties of the individual systems. I will discuss our group’s latest efforts to develop high-efficiency QD single photon sources and quantum transducers based on epitaxial QDs imbedded in GHz acoustic resonators.

Bio: Kevin Silverman leads the Quantum Nanophotonics Group at the National Institute of Standards and Technology in Boulder, CO. He received his B.S. in physics from Bucknell University in 1996, followed by M.S. and Ph.D. degrees in physics from the University of Colorado at Boulder in 2000 and 2002, respectively. His current research focuses on developing deterministic single-photon sources and microwave-to- optical transducers based on epitaxial quantum dots (QDs). His team specializes in molecular beam epitaxy, nanofabrication, and precision spectroscopy of optical nanostructures on GaAs substrates.
