Physics and Hardware for Intelligence

Summary

Combining integrated photonics with superconducting electronics is a promising approach to achieving large-scale neuromorphic systems. Optical signals broadcast over a network of nanophotonic waveguides enable massive connectivity between artificial neurons. Superconducting single-photon detectors integrated with waveguides enable extraordinary energy efficiency. Together, neurons based on these devices can achieve the complexity and connectivity of the human brain. We are currently developing the devices and systems to enable this extremely promising technology for large-scale neuromorphic computing.

Opportunities:

We currently have opportunities for postdocs. NIST Boulder and the University of Colorado are within walking distance of each other, creating a vibrant intellectual and scientific community. With over 300 sunny days per year and ample opportunities for outdoor and cultural recreation, Boulder is an excellent place to live. The salary of a starting postdoc at NIST is $70,000, far superior to many academic postdoc salaries. Please contact Jeff Shainline (jeffrey.shainline [at] nist.gov) if you are interested in these opportunities.
