Effective generation of cat and kitten states
We present an effective method of coherent state superposition (cat state)
generation using single trapped ion in a Paul trap. The method is
experimentally feasible for coherent states with amplitude using
available technology. It works both in and beyond the Lamb-Dicke regime.Comment: 11 pages, 8 figure
Temporally multiplexed superposition states of continuous variables
We study non-Gaussian states generated by two-photon subtraction from a cw
squeezed light source. In a cw scheme one can subtract two photons from the
source with a designated time separation and can genarate temporally
multiplexed superposition states of continuous variables. We numerically study
the properties of these states in the light of bosonic interference in the time
domain. In an appropriate temporal mode amplified kittens are produced in a
region where the time separation is comparable with the correlation time of
squeezed packets.Comment: 12 pages, 10 figure
Mimicking a Kerrlike medium in the dispersive regime of second-harmonic generation
We find an effective Hamiltonian describing the process of second-harmonic
generation in the far-off resonant limit. We show that the dynamics of the
fundamental mode is governed by a Kerrlike Hamiltonian. Some dynamical
consequences are examined.Comment: 12 pages, 4 figures Submitted to Optics Communication
