Quantum materials and devices
Addressing research challenges in quantum science and technology through fundamental advances in physics, materials, engineering design, and prototype development
We utilize emerging quantum materials to enable new generations of microwave devices that will meet the requirements imposed on the control and readout of quantum computing hardware. While prioritizing areas of national importance, our research aims to fill the gap between fundamental research and application-oriented device development.
Research thrust areas
Our research focuses on:
- On-chip nonreciprocal device design, development, and application
- Nonreciprocal superconducting materials
- Topological materials and heterostructures
