A highly entangled seven-qubit state is reported that sheds some new light on a recent
conjecture by Borras et al (2007 J. Phys. A: Math. Theor. 40 13407). The seven-qubit state …

Different mathematics forms of entangled state can judge prepared many particles is if
entangled. Entangled state is a key role of quantum information technology. The more …

Contrary to A. Borras et al.'s [1] conjecture, a genuine maximally seven-qubit entangled state
is presented. We find a seven-qubit state whose marginal density matrices for subsystems of …

It is worth studying recurrence relation of multi-qubit states due to its benefits to the criterion
and measurement of quantum entanglement. Recently, Huang et al. presented an expand …

The topology of entanglement in multipartite states with translational invariance is discussed
in this article. Two global features are foundby which one can distinguish distinct states …

A generalization of the geometric measure of quantum discord is introduced in this article,
based on Hellinger distance. Our definition has virtues of computability and independence …
