The “QCAT” Research Group carries out interdisciplinary studies at the border of quantum optics and condensed matter. Our goal is discovering inspiring physical phenomena, investigating the capabilities of modern platforms and finding their potential applications in quantum technologies. The Group has a theoretical background but tightly collaborates with experimentalists. Our domain comprises systems built with integrated optical circuits and superconducting photon detectors, optical microcavities and two-dimensional nanomaterials (e.g. graphene).
