The silicon quantum computing group involves both experiments and theory related to silicon quantum dot spin qubits. The dots are fabricated in top-gated silicon-germanium heterostructures, grown and measured in our laboratory. Areas of interest include quantum information, quantum dot transport and coherence, and valley splitting. PIs include Mark Eriksson, Max Lagally, Don Savage, Robert Blick, Susan Coppersmith, Robert Joynt, and Mark Friesen.
