Further quantum designs

Beside MUBs (affine quantum designs, independent observables) and SIC POVMs (quantum designs of degree 1) there exist (also in the case r=1) further interesting special cases of quantum designs.

In the paper The finite Fourier Transform and projective 2-designs (arXiv: 2207.09922) (external link) it is shown, that for or prime dimensions d= 3 (mod 4) an eigenvector basis of the Fourier Matrix exists, such that by applying the Weyl-Heisenberg matrices to this, a projective 2-design is generated.
