Quantizing multi-qubit entanglement is important for quantum information processing communication. In this paper, we study the relations between concurrence and purity of multi-qubit of pure states through detail calculation. For the maximally entangled states, we find that the averaged purity reaches its minimum; the concurrence reaches its maximum. Such results can be applied in quantizing multi-qubit entanglement.

纯态多量子比特的并发性和纯度关系

量化多量子位纠缠对于量子信息处理通信很重要。在本文中，我们通过详细计算来研究纯态多量子比特的并发性和纯度之间的关系。对于最大纠缠态，我们发现平均纯度达到最小值；同意达到最大值。这样的结果可以应用于量化多量子位纠缠。
