论文摘要
我们研究了$（D+1）$概括的Pauli Dynalial Maps的凸组合，该地图在Hilbert dimension $ d $中。为了某些脱碳函数的选择，这些地图是不可理解的，并且在凸组合中也保持不变。对于以脱碳函数$（1-e^{ - ct}）/n $为特征的动态地图，带有脱碳参数$ n $和衰减因子$ c $，我们评估了混合后获得的可逆地图的分数，这被发现与Dimential usperexpully afterential hignally d $ d $ d $。
We study the convex combinations of the $(d+1)$ generalized Pauli dynamical maps in a Hilbert space of dimension $d$. For certain choices of the decoherence function, the maps are noninvertible and they remain under convex combinations as well. For the case of dynamical maps characterized by the decoherence function $(1-e^{-ct})/n$ with the decoherence parameter $n$ and decay factor $c$, we evaluate the fraction of invertible maps obtained upon mixing, which is found to increase superexponentially with dimension $d$.
