论文摘要
工程量子系统中的参数耦合是控制，操纵和增强各种平台中相互作用的强大工具。它使我们能够将不同能量尺度的系统互相通信。本简短的章节介绍了基本原理，并讨论了一些示例，说明人们如何设计具有比传统设置具有改进特性的参数放大器。显然，选定的示例是作者偏见的，文献中可以找到其他有趣的建议和实现。本章的重点是线性耦合的谐波振荡器之间的参数效应，但是，参数调制也适用于非线性耦合和非线性耦合系统。
Parametric couplings in engineered quantum systems are a powerful tool to control, manipulate and enhance interactions in a variety of platforms. It allows us to bring systems of different energy scales into communication with each other. This short chapter introduces the basic principles and discusses a few examples of how one can engineer parametric amplifiers with improved characteristics over conventional setups. Clearly, the selected examples are author-biased, and other interesting proposals and implementations can be found in the literature. The focus of this chapter is on parametric effects between linearly coupled harmonic oscillators, however, parametric modulation is also applicable with nonlinear couplings and anharmonic systems.
