Abstract
We introduce the notion of noncommutative spherical codes (in particular, noncommutative kissing number problem). We show that the one-line proof for a variant of the Delsarte-Goethals-Seidel-Kabatianskii-Levenshtein upper bound for spherical codes, derived by Pfender extends to Hilbert C*-modules.
