Quantum technologies such as quantum sensing and quantum computing have the power to revolutionize classical processes by making use of quantum phenomena. In recent years molecular Qubits have emerged as a true alternative to superconducting or defect-based systems given their uniform chemical identity and tailorability. To establish functional molecular quantum systems the integration of molecular Qubits into larger assemblies is of paramount importance. Our research focuses on integrating a large variety of organic and inorganic Qubits in extended and well controllable molecular assemblies.
