数值模拟了电磁脉冲在量子超材料（一种人造的、全局量子相干的光学介质）中的传播。我们表明，一个一维的量子超材料超导量子比特的基础上，初始化在一个容易达到的因式分解激发态，演示激光在微波范围内，伴随着量子比特状态的混沌化和产生高次谐波。这些效应可以为量子超材料原型的表征和优化提供工具。
Electromagnetic pulse propagation in a quantum metamaterial, an artificial, globally quantum coherent optical medium, is numerically simulated. We show that a one-dimensional quantum metamaterial based on superconducting quantum bits, initialized in an easily reachable factorized excited state, demonstrates lasing in the microwave range, accompanied by the chaotization of qubit states and generation of higher harmonics. These effects may provide a tool for characterization and optimization of quantum metamaterial prototypes.
