我们描述了一个通用的技术，允许一个诱导和控制强相互作用的相邻原子的自旋态的光学晶格。我们表明，自旋交换相互作用的性质，如幅度，符号和各向异性，可以通过调整光学势来设计。我们说明了这种技术可以被用来有效地“工程师”量子自旋系统所需的属性，从可扩展的量子计算探测模型与复杂的拓扑结构，支持异国情调的任意子激发的具体例子。
We describe a general technique that allows one to induce and control strong interaction between spin states of neighboring atoms in an optical lattice. We show that the properties of spin exchange interactions, such as magnitude, sign, and anisotropy, can be designed by adjusting the optical potentials. We illustrate how this technique can be used to efficiently "engineer" quantum spin systems with desired properties, for specific examples ranging from scalable quantum computation to probing a model with complex topological order that supports exotic anyonic excitations.
