Quantum Properties of the Superposition of Excited Coherent States
LU Dao-ming · Jisuan wuli · 2006
The superposition of two excited coherent states with identical intensity and different phases are constructed.Its antibunching effect and amplitude-squared squeezing are studied numerically.The result shows that as the light intensity and the excited photon number increase,the antibunching effect decreases and the amplitude-squared squeezing increases.The amplitude-squared squeezing is influenced by the phase difference.
