On maximal entanglement between two pairs in four-qubit pure states
arXiv:0704.2961 · doi:10.1088/1751-8113/40/29/018
Abstract
We show that the state with the highest known average two-particle von Neumann entanglement entropy proposed by Sudbery and one of the authors gives a local maximum of this entropy. We also show that this is not the case for an alternative highly entangled state proposed by Brown et al.
