Superconductive Electronics for Quantum-based Metrology
*Sam Benz1
  • National Institute of Standards and Technology, Boulder, Colorado, 80305 USA1

Sam Benz leads the Superconductive Electronics Group of NIST that develops state-of-the-art quantum voltage standard systems, technology, and measurement techniques for AC and DC voltage and primary electronic thermometry, which NIST provides to U.S. Industry and national and international measurement laboratories. The group also has research programs in superconducting high-speed computing and rf communications.

Dr. Benz grew up in Dubuque, Iowa, USA, received his B.A. from Luther College, Decorah, IA, in 1985 and his Ph.D. degree in physics from Harvard University in 1990. He is a Fellow of NIST, the American Physical Society (APS) and the Institute of Electrical and Electronics Engineers (IEEE). He has four patents and three U.S. Department of Commerce Gold Medals and received the 2016 IEEE Joseph F. Keithley Award in Instrumentation and Measurement.

Towards Ambient Superconductivity: Novel Hydrogen-Rich Materials
*Ranga Dias1
  • University of Rochester1

Ranga Dias received his B.S. in Physics from the University of Colombo, Sri Lanka in 2006 and his Ph.D. in Physics from Washington State University in 2013. He joined the University of Rochester as an Assistant Professor of Physics and Astronomy and Mechanical Engineering after a postdoctoral fellowship in the Department of Physics at Harvard University, where he investigated the quantum phenomena in hydrogens at extreme conditions at Silvera’s Lab. Dias is today's leading scientist in high pressure superconductivity. Selected by Time magazine in February for its 2021 Time100 Next annual list of 100 individuals who are shaping the future of their fields and defining the next generation of leadership, Dias was in the “Innovators” category for his creation of a room temperature superconductor at high pressures. Dias has received several awards including the National Science Foundation CAREER Award, recognizing his work in superconductivity.
