Beschreibung:
<jats:p>An <jats:italic>N</jats:italic>-tangle can be defined for the finite dimensional Hilbert space H = C<jats:sup>2N</jats:sup> , with <jats:italic>N </jats:italic>= 3 or <jats:italic>N</jats:italic> even.We give an orthonormal basis which is fully entangled with respect to this measure.We provide a spin Hamilton operator which has this entangled basis as normalized eigenvectors if <jats:italic>N </jats:italic>is even. From these normalized entangled states a Bell matrix is constructed and the cosine-sine decomposition is calculated. If <jats:italic>N </jats:italic>is odd the normalized eigenvectors can be entangled or unentangled depending on the parameters.</jats:p>
