Abstract: Spin qubits, due to their long coherence times, offer great promise for use in quantum computation. At the same time, rapidly manipulating, reading out, and coupling such qubits over long distances remain experimental challenges. In this talk I will discuss a scheme that uses a Cooper pair transistor to induce a strong, engineerable coupling between a spin qubit and photons in a superconducting microwave cavity. This scheme offers the potential to both read out and manipulate a spin qubit using only one to a few cavity photons.
