Dr. Andersen is an expert on superconducting qubits who provided the first demonstration of error detection and repeated error correction using a surface code architecture with transmons, and his group has recently shown coherent manipulation of an Andreev spin qubit in hybrid semiconductor-superconductor transmons. TU Delft has access to 3 dilution refrigerators, capable of measurements ranging from 0 – 10 GHz for transmon qubit measurements and 3 dilution refrigerators allowing for DC transport and charge reflectometry measurements. Device fabrication will be carried out at the state of the art cleanroom at the Kavli Nanolab.

In Qukit, Andersen takes the lead on exploring new device functionality and machanism that replaces conventional tunnelling Josephson junctions (JJs) with semiconductor-superconductor hybrid JJs, and embeds quantum dots(QDs) defined on various materials in superconducting circuits.
