How Stark units enter SIC overlaps
Ingemar Bengtsson, Gary McConnell
It has been observed that the mutual scalar products of the vectors in a SIC-POVM are given by algebraic units, and at least in some cases by square roots of Stark units. The full…

A Conjecture on Almost Flat SIC-POVMs
Ingemar Bengtsson, Markus Grassl
A well supported conjecture states that SIC-POVMs -- maximal sets of complex equiangular lines -- with anti-unitary symmetry give rise to an identity expressing some of its overlap…
