    "abstract": "We propose to measure the quantum state of a single mode of the radiation\nfield in a cavity---the signal field---by coupling it via a\nquantum-non-demolition Hamiltonian to a meter field in a highly squeezed state.\nWe show that quantum state tomography on the meter field using balanced\nhomodyne detection provides full information about the signal state. We discuss\nthe influence of measurement of the meter on the signal field.",
