以稳健的方式制备非经典态的能力对于超出标准量子极限的量子传感器是必不可少的。我们证明了贝叶斯最优控制能够找到控制脉冲，驱动捕获的里德堡原子到高度纠缠的格林伯格-霍恩-蔡林格状态。控制序列具有基于伊辛动力学的准可积性的物理直观的功能。它们可以在实验室实验中构建，从而使制备时间与系统尺寸非常有利地成比例。
The ability to prepare nonclassical states in a robust manner is essential for quantum sensors beyond the standard quantum limit. We demonstrate that Bayesian optimal control is capable of finding control pulses that drive trapped Rydberg atoms into highly entangled Greenberger-Horne-Zeilinger states. The control sequences have a physically intuitive functionality based on the quasi-integrability of the Ising dynamics. They can be constructed in laboratory experiments, resulting in preparation times that scale very favorably with the system size.
