    Project title: Fundamental studies in physics of quantum information and in nonlinear optics of few-cycle solitons

    Project number: PN‐II‐ID‐PCE‐2011‐3‐0083

    Contract number: 53/05.10.2011

    Abstract:

    The project proposes a study of some fundamental aspects of photon-matter interaction with application in physics of quantum information and in nonlinear optics of localized (solitonic) structures. The project deals with two main research directions related to (1) the intrinsic phenomenon of the physical information: the study of covariant quantum channels in the transmission of information; time evolution of quantum correlations (entanglement and discord) in two-mode Gaussian open quantum systems; the study of degree of polarization of two-mode photon Werner-type states, and, respectively, to (2) the carrier vectors for the transmission of information: studies of few-optical-cycle solitons with duration of only a few femtoseconds (existence and robustness of circularly polarized ultrashort optical pulses in both the long-wave and short-wave propagation regime).

    Objectives of the project:

    a. Study of new polarization effects of few-optical-cycle solitons emerging from taking into account the intrinsic vectorial nature of the optical field; Study of existence, stability, and robustness of vectorial, ultrashort optical solitons.

    b. Study of the general structure of covariant quantum channels which appear in the information transmission; Description of duality of covariant liftings and covariant quantum channels.

    c. Study of the influence of quantum fluctuations and dissipation on the entanglement (quantum correlations) and quantum discord for Gaussian bi-modal states; Application of the quantum Chernoff bound for evaluating the degree of polarization of two-mode photon Werner-type states.

    Expected results:

    - description of the time evolution of continuous variable quantum entanglement, by using the logarithmic negativity, and of Gaussian quantum discord for a system consisting of two non-interacting non-resonant bosonic modes embedded in a common thermal environment

    - description of the time evolution of continuous variable quantum entanglement, by using Peres–Simon necessary and sufficient condition for separability of two-mode Gaussian states, and of Gaussian quantum discord for a system consisting of two non-interacting bosonic modes, each one embedded in its own thermal reservoir

    - new polarization effects for few-cycle optical solitons emerging from taking into account the vectorial nature of the electromagnetic field

    - stability and robustness of vectorial few-cycle solitons during propagation in nonlinear optical media

    - description of ultrashort (few-cycle) optical solitons by using generic models beyond the slowly-varying-envelope approximation
