    "abstract": "Two mode squeezed states can be used to achieve Heisenberg limit scaling in\ninterferometry: a phase shift of $\\delta \\phi \\approx 2.76 / \u003c N \u003e$ can be\nresolved. The proposed scheme relies on balanced homodyne detection and can be\nimplemented with current technology. The most important experimental\nimperfections are studied and their impact quantified.",
