The goal of the QuEST project is to wire up quantum circuits with electrical wires. A practical quantum information processor should rely on the established method of electrical wires for on-chip communication. It should not rely on unscalable nearest-neighbor coupling between qubits, and while optical communication is a possibility, it is more well-suited for long-distance quantum communication as integrated optical technology is still far behind integrated electrical technology. We plan to strongly couple arbitrary qubits to metal wires using sophisticated resonators, or zero-point voltage “generators”, that far outperform standard transmission line resonators typically used for this task.
