Assistant Professor of Applied Physics
Shruti Puri is a theoretical quantum physicist working at the forefront of the fields of quantum computing and quantum information science. Puri’s theoretical treatment of error (noise) in quantum computing systems blends ideas from quantum physics with methods from computer science in an effort to preserve the fragile ecosystems of the quantum world from noise. Her research aims to make these quantum computing systems more robust in the face of noise, and her results to date have yielded some of the most important breakthroughs in the field in over a decade.

Puri’s landmark theoretical discovery of a new type of quantum bit—widely known across the field as a Kerr-cat—stores information in microwave photons (quanta of light). Kerr-cat is tailored to be robust against most errors induced by the environment, and the few remaining errors become relatively easy to correct. Her discovery of the Kerr-cat quantum bit has led her to explore new areas of application for quantum computing.
