Our efforts

Qubit Operation

We characterize and manipulate state of the art Si/SiGe or SiMOS qubit devices. These devices are professionally manufactured by our industry collaborator imec (Interuniversity Micro- electronics Centre, Belgium) and academic partner RWTH Aachen (Bluhm group).

Quantum Sensing

Single molecule magnets (SMMs) provide a great potential for the implementation of d- dimensional quantum digits (qudits). For application magnetic ion centers are embedded in an organic ligand shell. For readout the SMMs are coupled to an electron on a quantum dot formed in a two-dimensional quantum well inside a semiconductor hetero-structure. The chip is placed in a home-built dilution cryostat at 25mK.

Project Goals

We currently research on two projects:

• The first project focusses on the characterization of industrially manufactured qubits, which involves the evaluation of new Si qubit chips layouts in terms of stability, manipulation and qubit operations.
• The second project concentrates on pushing forward quantum sensing of molecular qudits. Here the step from ensemble measurements to single molecules is a major goal.

Both projects require hands-on work with the cryostat and measurement setup.

Profile

Candidates must have (or soon obtain) a master degree in Physics. You should have interest in performing original research with the ability to work both independently and as a team player. Integrating and training Bachelor's and Master's students is encouraged. Researchers get a status as scientific employee with a salary according to 75% TV-L E13 as a PhD candidate or 100% TV-L E13 as a Postdoc.
