我们提出了一个可行的方案，通过对与之相互作用的辅助磁通量子比特进行投影测量来冷却机械谐振器，我们发现基态冷却可以通过几个随机时间间隔的测量来实现。冷却效率几乎不依赖于任何两个连续测量之间的时间间隔。该冷却方案还对环境噪声具有鲁棒性。
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.
