A short introduction to unitary 2-designs
... for all possible pt , where the integral is taken with respect to the normalized spherical measure. Note that by definition, a t-design is also a (t − 1)-design, since all monomials can have degree at most t (as long as all degrees are identical). Spherical designs exist for all t and d [1]. Let us ...
