论文摘要
同步在自然界中无处不在。 Van der Pol振荡器一直是研究同步的喜爱模型。在这里，我们研究了深量子制度中的振荡器，其中非经典作用主导了动力学。我们的结果表明：（i）挤压驱动会失去其效果，（ii）噪声增强同步，（iii）同步是有界的，并且（iv）极限周期对强驱动不敏感。我们提出了一种同步度量，并通过分析进行计算。这些结果反映了量子和深度量子方案中同步之间的内在差异。
Synchronization occurs ubiquitously in nature. The van der Pol oscillator has been a favorite model to investigate synchronization. Here we study the oscillator in the deep quantum regime, where nonclassical effects dominate the dynamics. Our results show: (i) squeezed driving loses its effect, (ii) noise boosts synchronization, (iii) synchronization is bounded, and (iv) the limit-cycle is insensitive to strong driving. We propose a synchronization measure and analytically calculate it. These results reflect intrinsic differences between synchronization in the quantum and deep quantum regimes.
