Abstract

We show how to dissipatively stabilize the quantum state of $N$ mechanical resonators in an optomechnical system, where the resonators interact by radiation pressure with $N$ optical modes, which are driven by properly selected multifrequency drives. We analyze the performance of this approach for the stationary preparation of Gaussian cluster states.
