Welcome to the
Minnich Group

Our group focuses on the growth and processing of thin-film electronic and quantum materials. We work at the intersection of materials science, engineering, 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.

Future transformative solid-state technology exploiting quantum effects such as entanglement will require new methods to grow and process highly delicate quantum materials into functioning devices. Our group’s present research focuses on inventing these methods and applying them to the fabrication of novel solid-state quantum technologies.


We are developing transistor microwave amplifiers with ultra low-noise performance into the millimeter-wave spectrum.


We are developing atomic layer etching processes which will enable subtractive manufacturing of electronic and quantum devices with atomic precision for the first time.


We are developing a new method for the epitaxial growth of thin-film quantum materials by laser-based evaporation of refractory elements.

APh 138b: Quantum Hardware and Techniques

This class covers multiple quantum technology platforms and related theoretical techniques, and will provide students with broad knowledge in quantum science and engineering. It will be split into three-week modules covering: applications of near-term quantum computers, superconducting qubits, trapped atoms and ions, topological quantum matter, solid state quantum bits, tensorproduct states.
