论文摘要
在两个Rydberg原子上的共振幅度调制场中，我们提出了Rydberg Antiblockade（RAB）制度，其中诱发了集体地面和激发态之间的Rabi振荡。可以通过RABI循环产生受控的Z门。此外，通过修改参数关系来解决RAB门的几个常见问题。通过形状脉冲增强了栅极保真度和对控制误差的栅极鲁棒性。 Rydberg-Rydberg相互作用强度的控制精度的要求是放松的。另外，原子激发受到约束，因此对原子衰变的栅极鲁棒性得到了增强。
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 the 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 the atomic decay is enhanced.
