Claim 7:
8. The system of claim 7, wherein the one or more spurious photon dissipation processes of the multiplexed control circuit that lead to cross talk further comprise:
effective Hamiltonians of the multiplexed control circuit that induce coherent errors,, wherein:
the mechanical resonators, the multiplexed control circuit, additional mechanical resonators, and one or more additional multiplexed control circuits, implement a surface code,
respective ones of the respective multiplexed control circuits are coupled to five phononic modes provided by a set of the mechanical resonators that implement the surface code,
the five phononic modes comprise two data modes, two ancilla modes, and a readout mode,
the respective ones of the multiplexed control circuits stabilize two data modes and two ancilla modes, and
timing of stabilizations performed for the surface code by the respective multiplexed control circuits are timed such that a target mode of a CNOT gate stabilized by a given multiplexed control circuit is also coupled to a control mode of the CNOT gate stabilized by the same given multiplexed control circuit.
