| Abstract: | Analyzed the technique of homodyne detection for Gaussian - modulated coherent states. The best effect was balance homodyne detection. In the theory of quantum, we studied the principle of Gaussian - modulated coherent with homodyne measurement, decided the relation between photon number with phase, elaborate the measurement technique of coherent, analyzed the signal and its variance. |
