我们证明了即使只有一部分纠缠态暴露在噪声环境中，量子关联也会发生突变。我们的结果通过不同的噪声环境单独作用于量子系统的单个量子比特来说明。因此，量子系统整体上的复合噪声并不是量子关联发生突变的必要条件。
We show that the sudden change of quantum correlation can occur even when only one part of the composite entangled state is exposed to a noisy environment. Our results are illustrated through the action of different noisy environments individually on a single qubit of quantum system. Composite noise on the whole of the quantum system is thus not the necessarily condition for the occurrence of sudden transition for quantum correlation.
