摘要:

囚禁原子离子的集合代表了相互作用自旋网络和量子磁性的量子模拟的最有吸引力的平台之一。自旋相关的光偶极力施加到离子晶体创建远程有效的自旋-自旋相互作用,并允许具有非平凡的相位和动力学的自旋哈密顿的模拟。在这里,我们展示了如何适当的设计激光场可以提供任意多维自旋-自旋相互作用图,即使是离子的线性空间阵列的情况下。该方案使用现有的陷阱技术,并可扩展到经典的模拟方法是棘手的水平。

英文摘要:

A collection of trapped atomic ions represents one of the most attractive platforms for the quantum simulation of interacting spin networks and quantum magnetism. Spin-dependent optical dipole forces applied to an ion crystal create long-range effective spin-spin interactions and allow the simulation of spin Hamiltonians that possess nontrivial phases and dynamics. Here we show how appropriate design of laser fields can provide for arbitrary multidimensional spin-spin interaction graphs even for the case of a linear spatial array of ions. This scheme uses currently existing trap technology and is scalable to levels where classical methods of simulation are intractable.
