Quantum engineeringin the solid state

Welcome to the Zhang Hybrid Quantum Systems Lab!
We are a new experimental group working in quantum information science. We combine superconducting circuits, nanomechanics, and quantum defects to explore and engineer quantum systems for sensing and information processing.

How we work

Across platforms, down to mechanisms

Our group works at the boundary of physics, electrical engineering, and materials science. We connect device design, nanofabrication, low-temperature measurement, and microscopic materials characterization to understand—and ultimately engineer—the limits of quantum coherence.
