# Codes and Expansions (CodEx) Seminar

## Hanmeng (Harmony) Zhan (York University)DRACKNs and their applications in quantum information

A DRACKN is a distance regular antipodal cover of the complete graph $K_n$. In this talk, I will discuss two applications of DRACKNs in quantum information: providing equiangular right frames, and generating entanglement in quantum walks. The first part was joint work with Coutinho, Godsil and Shirazi, and the second part with Chan, Coutinho, Drazen, Eisenberg, Godsil, Lippner, Kempton, and Tamon.
