Abstract
A spin bus quantum computing architecture includes a spin bus formed of multiple strongly coupled and always on qubits that define a string of spin qubits. A plurality of information bearing qubits are disposed adjacent a qubit of the spin bus. Electrodes are formed to the information bearing qubits and the spin bus qubits to allow control of the establishment and breaking of coupling between qubits to allow control of the establishment and breaking of coupling between each information bearing qubit and the spin bus qubit adjacent to it. The spin bus architecture allows rapid and reliable long-range coupling of qubits.
