论文摘要
我们描述了由光学捕获的分子和原子的混合阵列组成的量子信息结构。该设计利用了rydberg原子的大型过渡偶极矩介导相干分子自由度编码的量子位之间的快速,高保真门。讨论了引起,衰减,脉搏面积噪声和向其他分子状态泄漏的误差通道。分子 - rydberg的相互作用也可用于实现非破坏性分子检测和旋转状态读数。我们考虑使用NACS分子和CS Rydberg原子对该方案进行特定的近期实施,这表明可以实施300 〜NS大门,其潜在的忠诚度为$> 99.9 \%$。
We describe a quantum information architecture consisting of a hybrid array of optically-trapped molecules and atoms. This design leverages the large transition dipole moments of Rydberg atoms to mediate fast, high-fidelity gates between qubits encoded in coherent molecular degrees of freedom. Error channels of detuning, decay, pulse area noise, and leakage to other molecular states are discussed. The molecule-Rydberg interaction can also be used to enable nondestructive molecule detection and rotational state readout. We consider a specific near-term implementation of this scheme using NaCs molecules and Cs Rydberg atoms, showing that it is possible to implement 300~ns gates with a potential fidelity of $> 99.9\%$.
