使用一个控制良好的量子系统来模拟复杂的量子物质是一个已经存在了30年的想法，并且在超冷原子系统中付诸实践已经有十多年了。最近的兴奋点集中在使用超导电路的量子模拟器的新实现上，传统的微芯片制造可以用于快速灵活地将设计概念带到实验现实中。由于这些模拟器中的量子“粒子”是电路激发，而不是受守恒定律约束的物理粒子，超导模拟器通过自然地访问非平衡物理学来补充超冷原子。在这里，我们回顾了最近的财富的理论探索和实现这些新器件的实验前景。
Using a well-controlled quantum system to simulate complex quantum matter is an idea that has been around for 30 years and put into practice in systems of ultracold atoms for more than a decade. Much recent excitement has focused on a new implementation of quantum simulators using superconducting circuits, where conventional microchip fabrication can be used to take design concepts to experimental reality, quickly and flexibly. Because the quantum 'particles' in these simulators are circuit excitations rather than physical particles subject to conservation laws, superconducting simulators provide a complement to ultracold atoms by naturally accessing non-equilibrium physics. Here, we review the recent wealth of theoretical explorations and experimental prospects of realizing these new devices.
