The Special Quantum Character of the Two-Photon Coherent State from the Ideal Squeezed State
Zhu Hong · Zhongyang Minzu Daxue xuebao · 2004
We investigate the average number of photons in the two-photon coherent state by comparison with the ideal squeezed state and find that it relates to the quantum fluctuation of the quadrature and the phase of the initial coherent state. The physical significance of the relations is analyzed in detail.
