Claim 0:
1. A system comprising:
a plurality of mechanical resonators;
a multiplexed control circuit coupled with the mechanical resonators configured to stabilize arbitrary coherent state superpositions (cat states) of the mechanical resonators, wherein to stabilize the cat states, the multiplexed control circuit is configured to:
drive respective storage modes of the respective mechanical resonators; and
dissipate phonons from the respective mechanical resonators via an open transmission line coupled to the multiplexed control circuit that is configured to absorb photons from a dump mode of the multiplexed control circuit,
wherein the mechanical resonators are detuned such that phonons supplied from the multiplexed control circuit are supplied in an incoherent manner; and

one or more filters configured to suppress one or more spurious photon dissipation processes of the multiplexed control circuit that lead to cross-talk between the storage modes of the respective mechanical resonators if not suppressed.
