我们根据经典的基于阻容分流(RCSJ)结模型的Josephson电路量子行为的实验结果进行了研究。我们的分析表明，脉冲微波驱动约瑟夫森结在低温和低耗散下的非线性行为与约瑟夫森电路的实验观察结果非常相似。具体地说，我们证明拉比振荡、拉姆齐条纹和自旋回波观测不是具有独特量子解释的现象。事实上，它们是经典非线性动力学中瞬变到锁相的自然结果，当遵循微波应用的实验配方和实验探测方案时，可以在纯经典约瑟夫森结模型中观察到。因此，我们认为经典非线性动力学有助于理解在极低温和低耗散条件下对各种微波扰动的约瑟夫森响应的相关实验观测。

英文摘要：
We investigate the results of recently published experiments on the quantum behavior of Josephson circuits in terms of the classical modelling based on the resistively and capacitively-shunted (RCSJ) junction model. Our analysis shows evidence for a close analogy between the nonlinear behavior of a pulsed microwave-driven Josephson junction at low temperature and low dissipation and the experimental observations reported for the Josephson circuits. Specifically, we demonstrate that Rabi-oscillations, Ramsey-fringes, and spin-echo observations are not phenomena with a unique quantum interpretation. In fact, they are natural consequences of transients to phase-locking in classical nonlinear dynamics and can be observed in a purely classical model of a Josephson junction when the experimental recipe for the application of microwaves is followed and the experimental detection scheme followed. We therefore conclude that classical nonlinear dynamics can contribute to the understanding of relevant experimental observations of Josephson response to various microwave perturbations at very low temperature and low dissipation.
