Therefore, an experimental technique to generate squeezed vacuum and coherently displaced squeezed states is presented. In order to characterize nonclassical states, a new experimental technique, the homodyne cross correlation measurement, was realized, showing a so far unknown insight into the quantumness of a squeezed state. Also, an experimentally accessible witnessing approach for the degree of nonclassicality is presented for arbitrary quantum states.<eng> vorgelegt von: Melanie Schünemann, geb.
