    "abstract": "Quantum correlations between bright pump, signal, and idler beams produced by\nan optical parametric oscillator, all with different frequencies, are\nexperimentally demonstrated. We show that the degree of entanglement between\nsignal and idler fields is improved by using information of pump fluctuations.\nThis is the first observation of three-color optical quantum correlations.",
