约瑟夫森电路实现量子信号的量子限制参量放大

Introduction to Quantum-limited Parametric Amplification of Quantum Signals with Josephson Circuits

Michel Devoret, Ananda Roy

摘要:

这篇简短而固执己见的评论从微波频率下量子信号的概念开始,重点放在线性参量放大的原理上。放大过程是由约瑟夫森结的色散非线性引起的。我们讨论了这些放大器的两个定义特性:接收信号、闲频和泵浦波的模式的数量,以及这些波进入电路的独立端口的数量。

英文摘要:

This short and opinionated review starts with a concept of quantum signals at microwave frequencies and focuses on the principle of linear parametric amplification. The amplification process arises from the dispersive nonlinearity of Josephson junctions driven with appropriate tones. We discuss two defining characteristics of these amplifiers: the number of modes receiving the signal, idler and pump waves and the number of independent ports through which these waves enter into the circuit.
