摘要： The effect of an imperfect system on the measurement of squeezing is studied. It is shown that the imperfectly efficient detectors and the unbalance of the beam-splitter will reduce the measured squeezing. The effects on quadrat ure phase squeezing and photon number squeezing are different from the usual balanced homodyne detection.
