我们通过简单的计算证明，即使在理想的弱噪声下，二分开放量子系统的弛豫也包含以前在量子噪声物理学中未遇到的元素。虽然众所周知，衰减率的可加性对于单个系统的退相干是通用的，但我们证明，即使是最简单的复合系统的二分相干性，它也会崩溃。
We demonstrate in straightforward calculations that even under ideally weak noise the relaxation of bipartite open quantum systems contains elements not previously encountered in quantum noise physics. While additivity of decay rates is known to be generic for decoherence of a single system, we demonstrate that it breaks down for bipartite coherence of even the simplest composite systems.
