论文摘要
在这项工作中，我们使用高斯振幅调制和恒定的激光频率在线性链条上设计和实现了频率的Molmer-Sorensen大门。我们选择此频率以平衡栅极期间所有运动模式的纠缠积累，即使对于长离子链，也会产生强大的频率误差。我们在三离子链上演示了这项技术，从$ 20 \ $ 20 \，$ kHz的频率偏移范围降低了$ <\，1 \％$降低，我们通过对两到33个离子的链进行数值模拟来分析此门设计的性能。
In this work, we design and implement frequency-robust Molmer-Sorensen gates on a linear chain of trapped ions, using Gaussian amplitude modulation and a constant laser frequency. We select this frequency to balance the entanglement accumulation of all motional modes during the gate to produce a strong robustness to frequency error, even for long ion chains. We demonstrate this technique on a three-ion chain, achieving $<\,1\%$ reduction from peak fidelity over a $20\,$kHz range of frequency offset, and we analyze the performance of this gate design through numerical simulations on chains of two to 33 ions.
