Photon-added and photon-subtracted displaced Fock states and their non-classical properties
Si Kun, Miao Zhang, Jia Huan-Yu · Chinese Physics B · 2009
A new kind of quantum optical state, photon-added and -subtracted displaced Fock states, is introduced by applying the inverse of bosonic creation and annihilation operators to displaced Fock states. The quantum statistical properties of these states are investigated by numerical methods. Numerical results indicate that these states reveal some interesting non-classical properties, such as anti-bunching effects, sub-Poisson distributions and negativities of their Wigner functions.
