Q-Lab

The research topics at imo-imomec/imec Q-Lab division span over different quantum technology domains, with a particular focus on solid-state spin qubits in diamond and other wide-bandgap materials. Our activities include the fabrication of quantum-grade diamond, the engineering of spin defects in wide-bandgap materials, the implementation of photoelectrically read-out qubits and the development of diamond-based devices for quantum sensing, quantum communication and quantum information processing.
