    "abstract": "We present an optical scheme that realizes the standard von Neumann\nmeasurement model, providing an indirect measurement of a quadrature of the\nfield with controllable Gaussian state-reduction. The scheme is made of simple\noptical elements, as laser sources, beam splitters, and phase sensitive\namplifiers, along with a feedback mechanism that uses a Pockels cell. We show\nthat the von Neumann measurement is achieved without the need of working in a\nultra-short pulsed regime.",
