Quantum entanglement in n-qubit real equally weighted states    [PDF]

Ri Qu, Yanru Bao

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.
