我们证明了孤立的宏观量子系统的平衡，准备在非平衡混合态与许多能级的显着人口，并观察到的仪器与合理的约束工作范围相比，分辨率限制。这两个属性都满足许多，如果不是全部，实验现实的条件。在平衡状态下，统计力学的预测和局限性得以恢复。
We demonstrate the equilibration of isolated macroscopic quantum systems, prepared in nonequilibrium mixed states with a significant population of many energy levels, and observed by instruments with a reasonably bound working range compared to the resolution limit. Both properties are satisfied under many, if not all, experimentally realistic conditions. At equilibrium, the predictions and limitations of statistical mechanics are recovered.
