Answering fundamental questions in physics and cosmology requires precision in measurement at or beyond the standard limits imposed by quantum mechanics. Our group’s overarching goal is to advance the science and technology of measurement that allows these questions to be answered. Our present research is divided into three thrusts.


Low noise transistor microwave amplifiers

We are developing transistor microwave amplifiers used in radio astronomy and other fields that operate near the standard quantum limit of noise. Read more here.


Transport and fluctuation phenomena in semiconductors

We are advancing ab-initio methods to compute high-field transport and fluctuation phenomena in solids without any adjustable parameters. Read more here.


Quantum simulation

We are developing algorithms for quantum simulation on near-term quantum hardware as well as examining how theoretical proposals for error correction schemes perform on near-term devices in the presence of non-idealities such as cross-talk. Read more here
