APS -2017 Annual Meeting of the APS Mid-Atlantic Section- Event - Squeezing Light with Atoms: Generation of Non-Classical Light via Four-Wave Mixing

摘要

The goal of the project is to produce a pair of polarization-entangled light fields using four-wave mixing in hot Rubidium vapor. In this process, interaction of atoms with near-resonant strong control optical field results in strong amplification of a weak probe optical field and in generation of a quantum correlated conjugate Stokes optical field. To establish the quantum correlation between the Stokes and probe fields, we measured the differential intensity noise between the Stokes and probe fields. If it falls below the quantum noise limit, then two-mode intensity squeezing has been achieved, as a first step toward realization of the polarization Bell states.
