The system of qubits interacting with the perturbation field of an arbitrary envelope in the Furry representation based on the Magnus expansion in quantum electrodynamics is investigated. The general expressions for quantum transitions for probabilit

The spectra of two photon generation in the process of spontaneous parametric down conversion are studied in a waveguide containing the nonlinear segments with the spatial chirp. Three photon parametric interaction is investigated for the waveguide c

In this Letter, the purity of quantum states is applied to probe chaotic dissipative dynamics. To achieve this goal, a comparative analysis of regular and chaotic regimes of nonlinear dissipative oscillator (NDO) are performed on the base of excitati

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 anal

We consider quantum dynamics of a parametrically driven anharmonic oscillator (PDAO) at a few-photon level. In this scheme the oscillatory mode is excited through the degenerate down-conversion process. This scheme could be experimentally realized in

We study the excitation of nonlinear dissipative oscillator under influence of a monochromatic force at the level of a few quanta. With this purpose we consider an optical parametric oscillator combined with phase-modulation in which the oscillatory
Resonance fluorescence from an asymmetric quantum dot dressed by a bichromatic electromagnetic field
We present the theory of resonance fluorescence from an asymmetric quantum dot driven by a two-component electromagnetic field with two different frequencies, polarizations and amplitudes (bichromatic field) in the regime of strong light-matter coupl

In spatially structured strong laser fields, quantum electrodynamical vacuum behaves like a nonlinear Kerr medium with modulated third-order susceptibility where new coherent nonlinear effects arise due to modulation. We consider the enhancement of v

The Fock states are usually generated by using interaction of oscillatory mode with atomic systems driven by a coherent field. We demonstrate that production of Fock states is also realized in the specific operational regimes of a single nonlinear os

We investigate two dimensional nonlinear aperiodic structures leading to multi quasi-phase-matching conditions and multi-frequency second-harmonic generation (SHG) in one chip. For arranging devices close to an experimental situation the intensities
