Nearly tight weighted 2-designs in complex projective spaces of every dimension
John Jasper, Dustin G. Mixon
We use dense Sidon sets to construct small weighted projective 2-designs. This represents quantitative progress on Zauner's conjecture.

Harmonic Grassmannian codes
Matthew Fickus, Joseph W. Iverson, John Jasper +1
An equi-isoclinic tight fusion frame (EITFF) is a type of Grassmannian code, being a sequence of subspaces of a finite-dimensional Hilbert space of a given dimension with the prope…

Phase retrieval and norm retrieval
Saeid Bahmanpour, Jameson Cahill, Peter G. Casazza +2
Phase retrieval has become a very active area of research. We will classify when phase retrieval by Parseval frames passes to the Naimark complement and when phase retrieval by pro…
