论文摘要
我们通过使用12个耦合的超导量量阵列报告了梯形定位连接的模拟模拟。为了执行模拟，我们制造了一个超导量子处理器，该量子处理器分为两个域：代表ergodic系统的驱动结构域，而第二个则位于疾病的效果下。由于局部和离域状态之间的重叠，对于小型疾病，存在邻近效应，并且定位被破坏。为了实验研究，我们在驱动域中准备微波炉激发，并探索它可以通过探测其动力学来穿透无序区域的深度。此外，我们进行了超过50多种疾病实现的集合平均值，这清楚地表明了接近性效应。我们的工作开辟了一条新的途径，以构建具有凝结物物理学和材料科学应用的驱动系统的量子模拟器
We report the analogue simulation of an ergodiclocalized junction by using an array of 12 coupled superconducting qubits. To perform the simulation, we fabricated a superconducting quantum processor that is divided into two domains: a driven domain representing an ergodic system, while the second is localized under the effect of disorder. Due to the overlap between localized and delocalized states, for small disorder there is a proximity effect and localization is destroyed. To experimentally investigate this, we prepare a microwave excitation in the driven domain and explore how deep it can penetrate the disordered region by probing its dynamics. Furthermore, we performed an ensemble average over 50 realizations of disorder, which clearly shows the proximity effect. Our work opens a new avenue to build quantum simulators of driven-disordered systems with applications in condensed matter physics and material science
