Informational power of the Hoggar SIC-POVM
arXiv:1512.01735 · doi:10.1103/PhysRevA.94.012122
Abstract
We compute the informational power for the Hoggar SIC-POVM in dimension 8, i.e. the classical capacity of a quantum-classical channel generated by this measurement. We show that the states constituting a maximally informative ensemble form a twin Hoggar SIC-POVM being the image of the original one under a conjugation.
