CALIFORNIA INSTITUTE OF TECHNOLOGY
Welcome to the
Minnich Group
Our group focuses on developing detectors based on semiconductor devices and superconducting circuits used in radio astronomy and other scientific applications. We work at the intersection of engineering, materials science, and physics. We are part of a vibrant quantum science and engineering environment at Caltech.
Our group is committed to promoting diversity, equity, and inclusion in our division, at Caltech, and in the research community.

Research
Answering fundamental questions in physics and cosmology requires continuous improvement of the noise performance of existing detector technologies as well as the development of fundamentally new types of detectors. Our group’s present research focuses on the solid-state physics and transport phenomena that govern the noise performance of various detectors, typically based on semiconductors and superconducting circuits at Caltech.
We are developing transistor microwave amplifiers used in radio astronomy and other fields that operate near the standard quantum limit of noise.
We are advancing ab-initio methods to compute high-field transport and fluctuation phenomena in solids without any adjustable parameters.
We are developing atomic layer etching (ALE) processes for various dielectrics and metals and applying them to devices such as superconducting microresonators. By careful engineering of the surface region with atomic precision, we will be able to push the performance of detectors towards their intrinsic upper limit.
We are exploring how near-term quantum computers may be used for quantum simulation of physically relevant systems.
