US 7,613,765 B1 · Bus architecture for quantum processing

Abstract

A quantum processing apparatus includes a qubit, a superconducting bus, and a controllable coupling mechanism that controllably couples the superconducting bus to the qubit. The controllable coupling mechanism is characterized by a first state in which the superconducting bus and the qubit are capacitively coupled, thereby permitting a coupling operation to be performed between a quantum device, coupled to the superconducting bus, and the qubit. The controllable coupling mechanism is also characterized by a second state in which the superconducting bus and the qubit are capacitively uncoupled such that the qubit and the quantum device are not coupled to each other.
