    "abstract": "We present a new technique for the detection of two-mode squeezed states of\nlight that allows for a simple characterization of these quantum states. The\nusual detection scheme, based on heterodyne measurements, requires the use of a\nlocal oscillator with a frequency equal to the mean of the frequencies of the\ntwo modes of the squeezed field. As a result, unless the two modes are close in\nfrequency, a high-frequency shot-noise-limited detection system is needed. We\npropose the use of a bichromatic field as the local oscillator in the\nheterodyne measurements. By the proper selection of the frequencies of the\nbichromatic field, it is possible to arbitrarily select the frequency around\nwhich the squeezing information is located, thus making it possible to use a\nlow-bandwidth detection system and to move away from any excess noise present\nin the system.",
