Scaling Up Quantum Computation with Molecular Spins (SUMO)

The goal of the project SUMO is to develop the basis for a robust quantum technology. For this purpose two physical quantum system are combined, such that their advantages are complemented: On the one hand, superconducting resonators, which have the advantage of being very flexible. Additionally, superconductivity provides very low losses and therefore low decoherence. On the other hand, molecules have good coherence properties, which hardly change from molecule to molecule. Moreover, several qubits can be implemented on one molecule. The projects aims to advance in two directions: First, the realisation of complex calculations with a molecule, in notably the detection and correction of errors. Second, the strong coupling of molecules to a superconducting resonator. In particular, new molecules will be synthesized containing several physical qubits and we will improve the coherence properties. Furthermore, we will develop novel superconducting nanoresonators that couple much stronger to the molecules. Finally, the systems will be combined in order to allow complex quantum opertions.
