    "abstract": "A self-homodyne detection scheme is proposed to perform two-mode tomography\non a twin-beam state at the output of a nondegenerate optical parametric\namplifier. This scheme has been devised to improve the matching between the\nlocal oscillator and the signal modes, which is the main limitation to the\noverall quantum efficiency in conventional homodyning. The feasibility of the\nmeasurement is analyzed on the basis of Monte-Carlo simulations, studying the\neffect of non-unit quantum efficiency on detection of the correlation and the\ntotal photon-number oscillations of the twin-beam state.",
