Nondeterminstic ultrafast ground state cooling of a mechanical resonator
arXiv:1103.4197 · doi:10.1103/PhysRevB.84.094502
Abstract
We present an ultrafast feasible scheme for ground state cooling of a mechanical resonator via repeated random time-interval measurements on an auxiliary flux qubit. We find that the ground state cooling can be achieved with \emph{several} such measurements. The cooling efficiency hardly depends on the time-intervals between any two consecutive measurements. The scheme is also robust against environmental noises.
