使用马尔可夫主方程方法研究了耗散对量子态宏观叠加的影响。结果表明，两种状态的叠加以与两种状态之间的分离成正比的速率减少为混合。这凸显了在实践中观察宏观量子态叠加的难度。
The effect of dissipation on a macroscopic superposition of quantum states is studied with use of a Markovian master-equation approach. It is shown that a superposition of two states is reduced to a mixture at a rate proportional to the separation between the two states. This underlines the difficulty of observing a superposition of macroscopic quantum states in practice.
