We present a general approach for quantifying tolerance of a nonlocal -partite state to any local noise under different classes of quantum correlation scenarios with arbitrary numbers of settings and outcomes at each site. This allows us to derive new precise bounds in and on noise tolerances for: (i) an arbitrary nonlocal -qudit state; (ii) the -qudit Greenberger-Horne-Zeilinger (GHZ) state; (iii) the -qubit state and the -qubit Dicke states, and to analyse asymptotics of these precise bounds for large and d .
我们提出了一种通用方法，用于在不同类别的量子关联场景下，对具有任意数量设置和每个位点结果的非局域多体状态针对任何局部噪声的耐受性进行量化。这使我们能够在[具体文献或范围]中得出关于以下噪声耐受性的新的精确界限：（i）任意非局域多量子比特态；（ii）多量子比特格林伯格-霍恩-泽林格（GHZ）态；（iii）多量子比特[具体态]和多量子比特迪克态，并分析这些精确界限对于大的[具体参数]和d的渐近性质。
