论文摘要
我们为旋转波近似（RWA）推导了静态有效的Lindbladian，以耦合到谐波振荡器浴的驱动的非线性振荡器。相关的耗散效应可能解释了普通RWA模型的预测与最近的超导电路实验的结果之间的数量级差异。在我们的计算中发现的高阶耗散器对量子误差校正方案和参数过程具有重要的后果。
We derive the static effective Lindbladian beyond the rotating wave approximation (RWA) for a driven nonlinear oscillator coupled to a bath of harmonic oscillators. The associated dissipative effects may explain orders of magnitude differences between the predictions of the ordinary RWA model and results from recent superconducting circuits experiments on the Kerr-cat qubit. The higher-order dissipators found in our calculations have important consequences for quantum error-correction protocols and parametric processses.
