我们提出的证据表明，退相干可以产生一个平滑的量子到经典的非线性动力学系统的过渡。量子和经典演化的高分辨率跟踪揭示了相应观测值的期望值的差异。主方程的解表明，退相干破坏了Wigner分布中的量子干涉，并洗掉了经典分布中的精细结构，使两者更接近。量子和经典的期望值之间的对应关系也重新建立。
We present evidence that decoherence can produce a smooth quantum-to-classical transition in nonlinear dynamical systems. High-resolution tracking of quantum and classical evolutions reveals differences in expectation values of corresponding observables. Solutions of master equations demonstrate that decoherence destroys quantum interference in Wigner distributions and washes out fine structure in classical distributions, bringing the two closer together. Correspondence between quantum and classical expectation values is also reestablished.
