Quantum Device Research Team
The Superconducting Quantum Circuit Fabrication Facility

We manage the The Superconducting Quantum Circuit Fabrication Facility (Qufab). This facility operates a 4-inch device prototyping line and provides process utilization and prototyping services. Qufab is capable of handling superconducting qubits and circuits, superconducting digital-analog integrated circuits, and superconducting 3D implementations.
