A concise guide to complex Hadamard matrices
Wojciech Tadej, Karol Zyczkowski
abstract: Complex Hadamard matrices, consisting of unimodular entries with arbitrary
phases, play an important role in the theory of quantum information. We review
basic properties of complex Hadamard matrices and present a catalogue of
inequivalent cases known for dimension N=2,...,16. In particular, we explicitly
write down some families of complex Hadamard matrices for N=12,14 and 16, which
we could not find in the existing literature.
