Solid State Quantum Computing Using Nanostructured Logic Gates

Abstract

The main goal of this work has been the development, measurement, and understanding of quantum dot qubits in silicon/silicon-germanium. Our team has approached this goal from both experimental and theoretical perspectives, covering materials, coherence, qubit fabrication, and measurement. Achievements include the measurement of stable, low noise Coulomb Blockade in a two dimensional electron gas-based Si/SiGe quantum dot, measurement of spin coherence in silicon quantum wells, development of new schemes for spin measurement and robust quantum gates, measurement of valley states and the low-energy spectrum in Si/SiGe quantum wells, and theoretical understanding of several decoherence mechanisms.
