DESCRIPTION:Kartik Srinivasan  Center for Nanoscale Science and Technolog
 y National Institute of Standards and Technology\, Gaithersburg\, MD \nPh
 otonic quantum information science seeks to leverage quantum phenomena suc
 h as entanglement and superposition to measure\, communicate\, and compute
  in new and potentially very powerful ways. Some of the physical resource
 s required include the generation and measurement of quantum states of lig
 ht\, storage and manipulation of entanglement\, and transmission of quantu
 m information over long distances. Chip-integrated nanoscale photonic dev
 ices offer a path to realizing many such resources in a platform that can 
 potentially be mass-produced and operated outside of a laboratory environm
 ent. In this talk\, I will focus on two classes of quantum photonic techn
 ologies that we are developing based on chip-integrated nanophotonics. The
  first utilizes nonlinear wave-mixing in microresonators to enable the gen
 eration of photon pair states and to achieve frequency conversion of quan
 tum states of light\, including the ability to make spectrally distinct ph
 otons indistinguishable. The second utilizes single quantum emitters based
  on InAs/GaAs quantum dots for high-performance single-photon generation.
  I will end by discussing recent experiments at the intersection of the tw
 o technologies\, where single photons generated by a quantum dot are freq
 uency converted in a nonlinear microresonator\, and where single quantum d
 ot devices and nonlinear waveguides are heterogeneously integrated on a si
 ngle chip. \n\n \nBiography:\nKartik Srinivasan is a Project Leader at t
 he NIST Center for Nanoscale Science and Technology (CNST). He received B.
 S.\, M.S.\, and Ph.D. degrees in Applied Physics from the California Insti
 tute of Technology\, where his graduate research was supported by a Fanni
 e and John Hertz Foundation Fellowship. At the CNST\, he leads projects in
  the field of nanophotonics\, with a current focus on topics in photonic q
 uantum information science\, nonlinear optics\, and optical sensors. He h
 as been awarded the Presidential Early Career Award for Scientists and Eng
 ineers and is a Fellow of the Optical Society of America
