SICs: Extending the list of solutions

Abstract

Zauner's conjecture asserts that d2d^2 equiangular lines exist in all dd complex dimensions. In quantum theory, the d2d^2 lines are dubbed a SIC, as they define a favoured standard informationally complete quantum measurement called a SIC-POVM. This note supplements A. J. Scott and M. Grassl [J. Math. Phys. 51 (2010), 042203] by extending the list of published numerical solutions. We provide a putative complete list of Weyl-Heisenberg covariant SICs with the known symmetries in dimensions d90d\leq 90, a single solution with Zauner's symmetry for every d121d\leq 121 and solutions with higher symmetry for d=124,143,147,168,172,195,199,228,259d=124,143,147,168,172,195,199,228,259 and 323323.
