The quantum noise is well known as a physical final noise in optical communication system. No correction method for the error caused by the quantum noise has been known. In this paper, a correction method to the quantum noise is presented. The correction is in principle based on the polarization signal and polarization split detection. Because the method requires two polarization channels for signal transmission, it is not advantageous. Then a more efficient method for the transmission and correction which is based on the PSK signal and homodyne detection is presented. As result of application of the correction, it is shown that the error probability is brought to 0.
