论文摘要
$ {}^{133} \ mathrm {ba}^+$被从光学转换中遥不可及的激光器所照亮，并测量了由此产生的自发拉曼散射率。观察到的散射率低于以前的理论估计。大多数差异是通过对零散的状态光子密度进行更准确的处理来解释的。这项工作确定，与以前的模型相反，从激光引起的自发拉曼散射中对激光驱动的量子门没有基本限制。
${}^{133}\mathrm{Ba}^+$ is illuminated by a laser that is far-detuned from optical transitions, and the resulting spontaneous Raman scattering rate is measured. The observed scattering rate is lower than previous theoretical estimates. The majority of the discrepancy is explained by a more accurate treatment of the scattered photon density of states. This work establishes that, contrary to previous models, there is no fundamental limit to laser-driven quantum gates from laser-induced spontaneous Raman scattering.
