论文摘要
我们介绍了一个新型的方案系列，用于基于Rydberg封锁机制的中性原子量子的纠缠大门。这些协议通过一系列与Rydberg激发频率共鸣的全局激光脉冲实现受控的相对门。我们分析了这些方案，即它们的鲁棒性，以防止RABI频率或射击激光强度波动的校准误差，并表明它们在各种保真度度量中表现出稳健性。此外，我们讨论了这些协议的适应，以使它们对原子 - 动作诱导的多普勒变化进行鲁棒性。
We introduce a novel family of protocols for entangling gates for neutral atom qubits based on the Rydberg blockade mechanism. These protocols realize controlled-phase gates through a series of global laser pulses that are on resonance with the Rydberg excitation frequency. We analyze these protocols with respect to their robustness against calibration errors of the Rabi frequency or shot-to-shot laser intensity fluctuations, and show that they display robustness in various fidelity measures. In addition, we discuss adaptations of these protocols in order to make them robust to atomic-motion-induced Doppler shifts as well.
