A genuine maximally seven-qubit entangled state

Published 23 Oct 2011 in quant-ph | (1110.5011v1)

Abstract: 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 1,2- qubits are all completely mixed and for subsystems of 3-qubits is almost completely mixed.
