We load atoms into every site of an optical lattice and selectively spin flip atoms in a sublattice consisting of every other site. These selected atoms are separated from their unselected neighbors by less than an optical wavelength. We also show spin-dependent transport, where atomic wave packets are coherently separated into adjacent sites according to their internal state. These tools should be useful for quantum information processing and quantum simulation of lattice models with neutral atoms.
我们将原子加载到光晶格的每个位置,并在由每隔一个位置组成的子晶格中选择性地使原子自旋翻转。这些被选中的原子与未被选中的相邻原子之间的距离小于一个光波长。我们还展示了自旋相关的输运,其中原子波包根据其内部状态被相干地分离到相邻位置。这些工具对于用中性原子进行量子信息处理和晶格模型的量子模拟应该是有用的。
