    Photonic Quantum Interface between Subcarrier Wave and Polarization Encoding of Photonic Qubits

    We report a theoretical analysis of a photonic quantum interface, which makes it possible to deterministically convert photonic qubits from subcarrier wave to polarization encoding. The interface provides unam...

    Using Discrete Wavelet Analysis to Optimize a Random Number Generator Based on an InGaAs pi-n Photodiode in a Homodyne Scheme

    An approach is proposed for optimizing the operation of a random number generator based on discrete wavelet analysis. It is shown that controlling the contribution of the scale components of the wavelet transf...

    Using a Heterodyne Detection Scheme in a Subcarrier Wave Quantum Communication System

    The single photon detectors currently used in quantum communication schemes impose considerable restrictions on signal registration and dark count rates, require cooling to low temperatures, and are relatively...

    Selective laser spectroscopy of Mn4+-Mn4+ pair centers in SrTiO3 crystal

    Zero-phonon lines of a pair center of Mn4+ ions are observed in the luminescence and luminescence-excitation spectra of SrTiO3:Mn crystal. Based on the experimental data, the energy-level structure of the ground ...
