论文摘要
我们研究了具有任意数量的加速观察者的非稳态框架中N-Partite GHz和W状态的量子相干性及其分布。我们发现,GHz和W状态的连贯性随着无限加速度的限制而降低。相干性的冻结值取决于加速观察者的数量。 N-Partite GHz状态的连贯性是真正的全球性,并且在任何子系统中都不存在一致性。然而,对于N-Partite W状态,连贯性本质上是两部分类型,总相干性等于所有双方子系统的相干性总和。
We study the quantum coherence and its distribution of N-partite GHZ and W states of bosonic fields in the noninertial frames with arbitrary number of acceleration observers. We find that the coherence of both GHZ and W state reduces with accelerations and freezes in the limit of infinite accelerations. The freezing value of coherence depends on the number of accelerated observers. The coherence of N-partite GHZ state is genuinely global and no coherence exists in any subsystems. For the N-partite W state, however, the coherence is essentially bipartite types, and the total coherence is equal to the sum of coherence of all the bipartite subsystems.
