Mutually unbiased bases and generalized Bell states
A. B. Klimov, Сыч Денис Васильевич, Luis Lorenzo Sánchez-Soto, Gerd Leuchs · Physical Review A · 2009
We employ a straightforward relation between mutually unbiased and Bell bases to extend the latter in terms of a direct construction for the former. We analyze in detail the properties of these generalized Bell states, showing that they constitute an appropriate tool for testing entanglement in bipartite multiqudit systems.
