Quantum interference and diffraction in the phase space

  • C. M. A. Dantasox
  • B. Baseia


It is shown that a coherent superposition ofN squeezed states leads to a photon number distributionP n that is analogous to the classical result of interference and diffraction. The oscillations inP n coincide with those obtained in the classicalN-slits diffraction with a form-factor given by |(n|ψ)|2{sin(2nφn)/sin(2φn}2. Illustrative examples of particular superpositions are considered.

    Quantum interference and related effects coming from the superposition of iV-coherent states have been investigated in the literature. See,e.g.,Janszky J.,Domokos P. andAdams P.,Phys. Rev.
