Farfurnik’s research activities include the fundamental studies of optically-active solid-state spin systems (quantum dots and color centers) and the development of novel quantum technologies utilizing these systems. Farfurnik implements experimental protocols that control, characterize, and improve the quantum properties of spin systems. The resulting spins can be used for quantum sensing and for the studies of many-body dynamics. Farfurnik also utilizes nanofabrication tools to couple optically-active spins to photonic structures. Such coupling establishes efficient interfaces between spins and photons that form essential building blocks of quantum networks.
