| Abstract: | Preparation of nonclassical states that are described by negative Wigner functions is studied for an anharmonic oscillator under parametric excitation (AOPE). The over-transient pulsed regime of AOPE driven by a train of Gaussian laser pulses is analyzed. The results are obtained by complete consideration of dissipative and decoherence effects. |
