Single solid-state quantum emitter photonics for on-chip quantum information

Single solid-state quantum emitters have demonstrated considerable potential for the implementation of important quantum photonic devices such as on-demand single-photon sources or deterministic quantum logic gates. Converting a bare quantum emitter into a device with sufficient performance for use in quantum photonic systems requires an efficient, high cooperativity interface to accessing optical fields.

Such interfaces may in principle be implemented through nanophotonic geometries that leverage cavity quantum electrodynamics effects with strongly confined optical modes. A number of critical factors, however, such as preservation of the emitter coherence post-fabrication, and fabrication yield and scalability, must be simultaneously addressed, imposing significant challenges to device development. In this talk I will describe our past and current efforts to target such requirements through nanophotonic design, towards the development of scaled chip-integrated quantum photonic systems with functionality enabled by quantum emitters.

About Marcelo Davanco
Marcelo Davanco is a Project Leader in the NIST Microsystems and Nanotechnology Division. His current research interests are in the design, fabrication and characterization of integrated photonic interfaces to single solid-state quantum light emitters, towards applications in quantum information science and technology. He has co-authored over 60 journal papers and two book chapters, holds two patents, and has made many contributions to a wide range of research topics, such as photonic crystals and metamaterials, heterogeneous integrated photonic devices, integrated nonlinear optics and cavity optomechanics, and on-chip integrated quantum light emitters. Marcelo has B.S. and M.S. degrees in Electrical Engineering from the State University of Campinas (UNICAMP), Brazil, and a Ph.D. in Electrical and Computer Engineering from the University of California Santa Barbara in 2006.

About NIST
The National Institute of Standards and Technology (NIST) was founded in 1901 and is now part of the U.S. Department of Commerce. NIST is one of the nation’s oldest physical science laboratories. Congress established the agency to remove a major challenge to U.S. industrial competitiveness at the time — a second-rate measurement infrastructure that lagged behind the capabilities of the United Kingdom, Germany and other economic rivals.

From the smart electric power grid and electronic health records to atomic clocks, advanced nanomaterials and computer chips, innumerable products and services rely in some way on technology, measurement and standards provided by the National Institute of Standards and Technology.

Today, NIST measurements support the smallest of technologies to the largest and most complex of human-made creations — from nanoscale devices so tiny that tens of thousands can fit on the end of a single human hair up to earthquake-resistant skyscrapers and global communication networks.
