We consider the peculiarities of formation and registration of axially symmetric vortex fields in the context of applying diffractive optical elements such as vortex lenses and vortex axicons for the generation of single-photon states with a nonzero

The properties of the backward-wave spontaneous parametric down-conversion (SPDC) in a periodically poled potassium titanyl phosphate (KTP) waveguide are studied in the context of creating narrowband heralded sources of single-photon states. The effe

Abstract. We discuss the possibilities of controlling the spectrum of correlated photons generated via spontaneous parametric down-conversion by using external homogeneous electric field acting on the nonlinear crystal.

We analyze the single-qubit gates based on off-resonant Raman interaction when they are applied to qubits implemented as ensembles of active centers. We propose a new scheme which can be used to significantly decrease the influence of inhomogeneous b

The features of biphotons states generated via spontaneous four-wave mixing in nanofibers with a variable cross-section are studied. The spectral amplitude of the biphoton field is calculated and the effects of interference and phase modulation of th
