Patent ID: 8164082

Claim:
A spin bus QC architecture comprising: (a) a bus formed of multiple bus qubits extending in a string; (b) multiple information bearing qubits, each information bearing qubit formed adjacent to a bus qubit; (c) a first set of electrodes formed adjacent to the bus qubits and electronically coupled to a voltage supply, wherein the bus qubits, the first set of electrodes and the voltage supply are configured to turn on exchange interactions between each bus qubit and each of its neighboring bus qubits simultaneously; and (d) a second set of electrodes formed adjacent to the information bearing qubits and electronically coupled to a voltage supply, wherein the information bearing qubits, the second set of electrodes and the voltage supply are configured to selectively control the establishment and breaking of the exchange coupling between each information bearing qubit and the bus qubit adjacent to it, such that the spin bus QC architecture is configured to provide operations by turning exchange couplings between the information bearing qubits and their adjacent bus qubits on and off, while keeping the exchange couplings between each of the bus qubits and its neighboring bus qubits always on.
