  • Abstract
    We report on the preparation of entangled two mode squeezed states of yet unseen quality. Based on a measurement of the covariance matrix we found for the famous EPR-variance a value of 0.36. Furthermore, two mode quantum state tomography was used to extract single photon Fock states solely based on homodyne detection, demonstrating the strong quantum features of this entangled pair of laser beams. The probability for a single photon in this ensemble measurement exceeded 2/3.
