英文摘要	We present a feasible scheme for the cooling of a mechanical resonator via projective measurements on an auxiliary flux qubit which interacts with it. We find that ground-state cooling can be achieved with several random-time-interval measurements. The cooling efficiency hardly depends on the time intervals between any two consecutive measurements. The cooling scheme is also robust against environmental noise.
