Triangle Measure of Tripartite Entanglement

Although genuine multipartite entanglement has already been generated and verified by experiments, most of the existing measures cannot detect faithfully. In this work, exploiting for first time a previously overlooked constraint distribution in three-qubit systems, we reveal new tripartite measure, which is related to area so-called concurrence triangle. It compared with other found superior previous attempts different reasons. A specific example illustrated show that two can be inequivalent due high dimensionality Hilbert space. The properties triangle measure make it candidate potential quantum tasks available used any multiparty problems.
