论文摘要
模拟量子模拟器依靠可编程的量子设备来模仿描述各种物理现象的哈密顿量。光子耦合腔阵列是实现此类设备的有前途的平台。我们使用由8个高质量因子谐振器组成的硅光子耦合型腔阵列，并配备了专门设计的热岛岛加热器，以独立控制腔体，展示了可编程的设备，该设备实现了可访问完整的Eigen Energy-Energy Spectrum的紧密结合汉密尔顿人。我们报告说，与传统加热器相比，我们报告了腔阵列相邻位点之间的热串扰降低约50％，然后提出了一种控制方案，将腔阵列编程为给定的紧密结合的哈密顿量。
Analog quantum simulators rely on programmable quantum devices to emulate Hamiltonians describing various physical phenomenon. Photonic coupled cavity arrays are a promising platform for realizing such devices. Using a silicon photonic coupled cavity array made up of 8 high quality-factor resonators and equipped with specially designed thermo-optic island heaters for independent control of cavities, we demonstrate a programmable device implementing tight-binding Hamiltonians with access to the full eigen-energy spectrum. We report a ~50% reduction in the thermal crosstalk between neighboring sites of the cavity array compared to traditional heaters, and then present a control scheme to program the cavity array to a given tight-binding Hamiltonian.
