  1. We analyze the set of real and complex Hadamard matrices with additional symmetry constrains. In particular, we link the problem of existence of maximally entangled multipar-tite states of 2k subsystems with d levels each to the set of complex Hadamard matrices of order N = dk. To this end, we investigate possible subsets of such matrices which are, dual, strongly dual (H = HR or H = HΓ), two ...

In particular, we link the problem of existence of maximally entangled multipartite states of 2k 2 k subsystems with d d levels each to the set of complex Hadamard matrices of order N = dk N = d k.

  8. 1.1 Complex Hadamard Matrices A square matrix 𝐻 H italic_H with plus-or-minus 1 \pm 1 ± 1 entries is said to be a (real) Hadamard matrix [ 1], if its rows (or columns) are mutually orthogonal. This definition can be generalized by expanding the entries of 𝐻 H italic_H to a unit circle on the complex plane.
