Nonclassicality of radiation fields

In the previous chapter we discussed two important classes of the states of the radiation field, viz coherent states and Fock states. The coherent states were like classical states with well-defined amplitudes and phase. In addition, the relative fluctuation in photon number in a coherent state,

becomes smaller and smaller as n increases. Furthermore, all measurements with photo-detectors could not differentiate ...
