Structured Hadamard matrices and quantum information

Karol Zyczkowski, Jagiellonian University, Poland

Two classes of complex Hadamard matrices with certain special properties found recently applications in quantum physics. Consider a four index tensor $T_{ijkl}$ of size M. It can be reshaped into a square matrix $A_{\mu,\nu}$ of size $M^2$ with three different choices of composed indices e.g. $\mu=(i,j); \nu=(k,l)$ or $\mu=(i,k); \nu=(j,l)$, or $\mu=(i,l); \nu=(j,k)$.
