论文摘要
我们展示了如何使用状态依赖性的光电位将一对分子捕获在不同内部状态的分子，其分离比捕获光的波长小得多。这种紧密的间距大大增强了偶极 - 偶极相互作用，我们展示了如何使用它在分子之间实现比现有方案快100倍的分子之间的两倍大门，并且是已经证明的旋转相干时间。我们分析了由于超细结构，张量光移，光子散射和碰撞损失而引起的并发症，并得出结论，没有一个是实施该方案的障碍。
We show how state-dependent optical potentials can be used to trap a pair of molecules in different internal states at a separation much smaller than the wavelength of the trapping light. This close spacing greatly enhances the dipole-dipole interaction and we show how it can be used to implement two-qubit gates between molecules that are 100 times faster than existing protocols and than rotational coherence times already demonstrated. We analyze complications due to hyperfine structure, tensor light shifts, photon scattering and collisional loss, and conclude that none is a barrier to implementing the scheme.
