Circulant matrices with orthogonal rows and off-diagonal entries of absolute value $1$

Daniel Uzcátegui Contreras, Dardo Goyeneche, Ondřej Turek +1

It is known that a real symmetric circulant matrix with diagonal entries $d \geq 0$ , off-diagonal entries $\pm 1$ and orthogonal rows exists only of order $2 d + 2$ (and trivially of ord…

Coarse-grained entanglement classification through orthogonal arrays

Luigi Seveso, Dardo Goyeneche, Karol Życzkowski

Classification of entanglement in multipartite quantum systems is an open problem solved so far only for bipartite systems and for systems composed of three and four qubits. We pro…

A generalization of circulant Hadamard and conference matrices

Ondřej Turek, Dardo Goyeneche

We study the existence and construction of circulant matrices $C$ of order $n \geq 2$ with diagonal entries $d \geq 0$ , off-diagonal entries $\pm 1$ and mutually orthogonal rows. These…
