The distribution and evolution of quantum coherence for multi‐qubit W and GHz states of Dirac fields in the non‐inertial frames and under the action of local environments is studied. It is found that the N‐qubit W state has all orders of coherence (from bipartite to N‐partite subsystems), and the coherence of the whole system is equal to the sum of all the bipartite coherences in the whole time evolution. However, the evolved N‐qubit GHz state has its coherence belonged only to the whole system and no coherence resides in any subsystems. Further, it is found that the expressions of coherence for both W and GHz states are covariant with respect to the transformation of decaying rates.

非惯性框架中开放多量子位系统的量子相干分布和演化

研究了狄拉克场在非惯性框架中以及在局部环境的作用下，多量子位W和GHz状态的量子相干的分布和演化。发现N qubit W状态具有所有相干性阶次（从二分子系统到N子子系统），并且整个系统的相干性等于整个时间演化中所有二分相干性的总和。但是，演进的N比特GHz状态的相干性仅属于整个系统，而任何子系统中都没有相干性。此外，发现W和GHz状态的相干性表达相对于衰减率的变换是协变的。
