There is a significant ongoing effort in realizing quantum annealing with different physical platforms. The challenge is to achieve a fully programmable quantum device featuring coherent adiabatic quantum dynamics. Here we show that combining the well-developed quantum simulation toolbox for Rydberg atoms with the recently proposed Lechner-Hauke-Zoller (LHZ) architecture allows one to build a prototype for a coherent adiabatic quantum computer with all-to-all Ising interactions and, therefore, a platform for quantum annealing. In LHZ an infinite-range spin-glass is mapped onto the low energy subspace of a spin-1/2 lattice gauge model with quasi-local four-body parity constraints. This spin model can be emulated in a natural way with Rubidium and Caesium atoms in a bipartite optical lattice involving laser-dressed Rydberg-Rydberg interactions, which are several orders of magnitude larger than the relevant decoherence rates. This makes the exploration of coherent quantum enhanced optimization protocols accessible with state-of-the-art atomic physics experiments.

具有里德堡原子的相干量子退火器。

在使用不同的物理平台实现量子退火方面，正在进行大量的工作。挑战在于实现一种具有相干绝热量子动力学特性的完全可编程量子器件。在这里，我们证明，将发达的Rydberg原子量子模拟工具箱与最近提出的Lechner-Hauke-Zoller（LHZ）架构相结合，可以为具有全伊辛相互作用的相干绝热量子计算机构建原型，并且，因此，量子退火的平台。在LHZ中，将无限范围的自旋玻璃映射到具有准局部四体奇偶性约束的自旋1/2晶格规模型的低能量子空间。可以通过involving激光和里德伯格-里德伯格相互作用的二元光学晶格中的Rub原子和铯原子以自然方式模拟该自旋模型，比相关的退相干率大几个数量级。这使得对相干量子增强优化协议的探索可通过最新的原子物理实验进行。
