摘要
我们求解了多量子比特 W 型态的几何纠缠度的驻点方程。通过这种方式，我们解析计算了单参数量子比特和双参数四量子比特 W 型态及其最近积态的最大重叠。详细讨论了对任意 W 型态的可能推广以及这些结果的几何解释。

备注
V1:10 pages, 3 figures V2: 14 pages, one more section is added for the computation of the maximal overlap probability for the two-parametric W-state in 4-qubit system V3: 17 pages, one more 3-dimensional figure is added. Geometric interpretation of the maximal overlap probability is more clearly discussed
