    "abstract": "The quantum entanglement of amplitude and phase quadratures between two\nintense optical beams with the total intensity of 22mW and the frequency\ndifference of 1nm, which are produced from an optical parametric oscillator\noperating above threshold, is experimentally demonstrated with two sets of\nunbalanced Mach-Zehnder interferometers. The measured quantum correlations of\nintensity and phase are in reasonable agreement with the results calculated\nbased on a semi-classical analysis of the noise characteristics given by C.\nFabre et al.",
