    "abstract": "We consider an SU(1,1) interferometer employing four-wave mixers that is fed\nwith two-mode states which are both coherent and intelligent states of the\nSU(1,1) Lie group. It is shown that the phase sensitivity of the interferometer\ncan be essentially improved by using input states with a large photon-number\ndifference between the modes.",
