在Deutsch-Jozsa，Grover，Simon等量子算法中采用了n比特真实的等权态，我们定性地研究了n比特真实的等权态的纠缠特性.首先，根据结构度将所有n比特真实的等权态分为7部分。然后利用可分度和相似度分析了各部分态的多体纠缠特性。
The n-qubit real equally weighted states are employed in some quantum algorithms including Deutsch-Jozsa, Grover, Simon, and so on. We qualitatively investigate the entanglement properties of n-qubit real equally weighted states. Firstly, all of the n-qubit real equally weighted states are classified into 7 parts by means of their structural degrees. Then we analyze the multipartite entanglement features of the states in every part by means of separable and similar degrees.
