    "abstract": "This is a review of the problem of Mutually Unbiased Bases in finite\ndimensional Hilbert spaces, real and complex. Also a geometric measure of\n\"mubness\" is introduced, and applied to some recent calculations in six\ndimensions (partly done by Bjorck and by Grassl). Although this does not yet\nsolve any problem, some appealing structures emerge.",
