Abstract : The purpose of this research program was to develop a device architecture that is capable of coherently coupling two silicon spin qubits via the electromagnetic field of superconducting resonator. Single Electron spins can be efficiently coupled using the exchange interaction, but the strength of exchange falls of very quickly as a function of the distance separating the two electron spins. Cavity based coupling schemes have recently emerged as a robust tool for coupling superconducting quantum bits. The main goal of this research program was to make the first steps toward combing elements of the superconducting and semiconductor qubit architectures.
