AI 中文摘要
模拟量子仿真提供了一种研究强关联量子系统的有力方法，这些系统超出了经典计算的能力范围。在这种背景下，超冷原子气体已被证明是一个极其通用且易于控制的平台，可用于实现各种量子哈密顿量。在这项工作中，我们将这种控制水平扩展到一个多路复用配置，其中不同的量子仿真单元从单个原子云开始独立控制和设计。我们在两个代表性设置中展示了多路复用操作。首先，通过塑造盒式陷阱势并分别控制蒸发冷却轨迹，我们在整个幺正费米气体的超流转变过程中制备了处于不同温度的子系统。其次，我们展示了在具有单独可调参数的不同约瑟夫森结量子仿真单元上对约瑟夫森哈密顿量的并行量子仿真，包括用于初始化动力学的局部相位控制。我们的方案为系统研究强关联超冷物质中的动力学和输运哈密顿量提供了一条通用途径。此外，它很容易扩展到广泛的原子种类、几何结构和维度。
英文摘要
Analog quantum simulation offers a powerful way to study strongly correlated quantum systems that are beyond the reach of classical computation. In this context, ultracold atomic gases have been demonstrated to be an exceptionally versatile and well-controlled platform for implementing various quantum Hamiltonians. In this work, we extend this level of control to a multiplexed configuration in which distinct quantum-simulation units are independently controlled and engineered starting from a single atomic cloud. We demonstrate multiplexed operation in two representative settings. First, by shaping box-trap potentials and separately controlling the evaporative cooling trajectories, we prepare subsystems at various temperatures across the superfluid transition of the unitary Fermi gas. Second, we demonstrate parallel quantum simulation of the Josephson Hamiltonian across distinct Josephson-junction quantum simulation units with individually tunable parameters, including local phase control to initialize the dynamics. Our scheme provides a versatile route toward systematic studies of dynamics and transport Hamiltonians in strongly correlated ultracold matter. Moreover, it is readily extendable to a wide range of atomic species, geometries, and dimensionalities.
