论文摘要
我们在光学镊子中准备高达五十个费米原子的高填充两个组件阵列，每个镊子的地面运动状态处。使用频道镜技术，我们将阵列在各种二维几何形状中配置，并用可忽略的浮子加热。单个位点的全自旋和密度分辨的读数使我们能够在零熵的接近零熵初始状态后进行费米子量子模拟。我们在两乘二隧道耦合的哈伯德式盖子上准备一个相关状态，展示了所有用于实现可编程的费米子量子模拟器的构建块。
We prepare high-filling two-component arrays of up to fifty fermionic atoms in optical tweezers, with the atoms in the ground motional state of each tweezer. Using a stroboscopic technique, we configure the arrays in various two-dimensional geometries with negligible Floquet heating. Full spin- and density-resolved readout of individual sites allows us to post-select near-zero entropy initial states for fermionic quantum simulation. We prepare a correlated state in a two-by-two tunnel-coupled Hubbard plaquette, demonstrating all the building blocks for realizing a programmable fermionic quantum simulator.
