    Artistic illustration of opto-electric on-chip quantum circuit

    The world of quantum optics holds enormous potential to address a large variety of unsolved problems in sensing, information processing, computation, and precise measurements.

    Taking the advantage of well-developed nano fabrication processes, on-chip integrated

    quantum photonics is a promising platform for the realization of quantum optics technology.

    Extracting many-particle entanglement entropy from observables using supervised machine learning

    We study various topics related to basic quantum science, as well as quantum technologies. Currently, the main theme is quantum correlations which beg for a better theoretical understanding, as well as novel applications. The primary tool we
    use throughout our exploration is quantum optics.
