With a resonant amplitude-modulation field on two Rydberg atoms, we propose a Rydberg antiblockade (RAB) regime, where the Rabi oscillation between collective ground and excited states is induced. A controlled-Z gate can be yielded through a Rabi cycle. Further, several common issues of the RAB gates are solved by modifying the parameter relation. The gate fidelity and gate robustness against the control error are enhanced with a shaped pulse. The requirement of control precision of the Rydberg-Rydberg interaction strength is relaxed. In addition, the atomic excitation is restrained and therefore the gate robustness against atomic decay is enhanced.

Rydberg原子和鲁棒的高保真量子门具有共振振幅调制场的有效Rabi动力学。

通过在两个Rydberg原子上产生一个共振振幅调制场，我们提出了一种Rydberg反封锁（RAB）方案，其中引发了基态和激发态之间的Rabi振荡。可通过拉比循环产生可控Z门。此外，通过修改参数关系解决了RAB门的几个常见问题。利用整形脉冲增强了针对控制误差的栅极保真度和栅极鲁棒性。放松了对里德伯格-里德伯格相互作用强度的控制精度的要求。另外，抑制了原子激发，因此增强了抵抗原子衰减的栅极鲁棒性。
