论文摘要
我们介绍了柏拉图图上类似Ising的旋转的量子模拟实验，这些旋转是用二维阵列Rydberg原子和量子线耦合进行的。量子线用于近对偶联的长距离原子，从而使三维图的拓扑传播转换能够传给二维平面。我们实现了柏拉图固体的三个柏拉图型图，即四面体，立方体和八面体，并在准绝热控制汉密尔顿体系前后成功探测了它们的地面多体旋转构型，从顺磁相到反铁磁性阶段。我们对使用少于22个原子的小尺度量子模拟受到实验瑕疵的限制，这可以通过最先进的Rydberg-atom Technologies轻松改善1000多个原子量表。我们的量子线方法有望为大规模量子模拟铺平一条新的途径。
We present quantum simulation experiments of Ising-like spins on Platonic graphs, which are performed with two-dimensional arrays of Rydberg atoms and quantum-wire couplings. The quantum wires are used to couple otherwise uncoupled long-distance atoms, enabling topology-preserving transformtions of the three-dimensional graphs to the two-dimensional plane. We implement three Platonic graphs, tetrahedron, cube, and octahedron of Platonic solids, and successfully probe their ground many-body spin configurations before and after the quasi-adiabatic control of the system Hamiltonians from the paramagnetic phase to anti-ferromagnetic-like phases. Our small-scale quantum simulations of using less than 22 atoms are limited by experimental imperfections, which can be easily improved by the state-of-the-art Rydberg-atom technologies for more than 1000-atom scales. Our quantum-wire approach is expected to pave a new route towards large-scale quantum simulations.
