论文摘要
我们证明了通过模拟驱动型玻色 - 哈伯德模型的五个耦合人工原子的链条链的链条链链稳态传输的非平衡稳态传输。使用传输光谱法，我们表明该系统仍保持许多粒子相干性，尽管与两个开放空间耦合在一起。我们表明，使用Cross-Kerr相互作用可以通过高对比度可视化系统能带。对于消失障碍，我们观察到系统从线性到光子封锁的非线性状态的过渡与输入输出理论非常吻合。最后，我们展示了对系统引入的可控障碍如何抑制这种非本地光子传播。我们认为，提出的架构可以应用于多体浮动动力学的模拟模拟，甚至较大的人工原子铺平了一种替代量子至高无上的方式
We demonstrate non-equilibrium steady-state photon transport through a chain of five coupled artificial atoms simulating the driven-dissipative Bose-Hubbard model. Using transmission spectroscopy, we show that the system retains many-particle coherence despite being coupled strongly to two open spaces. We show that system energy bands may be visualized with high contrast using cross-Kerr interaction. For vanishing disorder, we observe the transition of the system from the linear to the nonlinear regime of photon blockade in excellent agreement with the input-output theory. Finally, we show how controllable disorder introduced to the system suppresses this non-local photon transmission. We argue that proposed architecture may be applied to analog simulation of many-body Floquet dynamics with even larger arrays of artificial atoms paving an alternative way to demonstration of quantum supremacy
