个人简介

My research is focused on hybrid quantum systems. In particular my interest is aimed at coupling superconducting quantum circuits to spins systems such as nitrogen-vacancy defects in diamond. This solid-state quantum optics platform allows us to study fundamental quantum effects such a as superradiance and bistability. Furthermore, this coupled system allows us to realize quantum technologies, such as microwave photon detectors and frequency transducers.
