US Patent 7613764 Methods for quantum processing

A method for performing a coupling operation between a quantum device and a qubit is provided. The quantum device is coupled to a superconducting bus. The method includes placing a controllable coupling mechanism into a coupled state, thereby coupling the quantum device and the qubit to each other. The quantum device or the qubit is then tuned for a first period of time. Then the controllable coupling mechanism is placed into an uncoupled state, thereby decoupling the quantum device and the qubit from each other.
