Job description:

We are looking for highly motivated scientists to work on experiments with superconducting qubits. These positions will be funded by the European Research Council (ERC) through the Advanced Grant „Millimeter-Wave Superconducting Quantum Circuits” - Milli-Q. The goal is to develop novel superconducting quantum circuits which are operating at frequencies one order of magnitude larger than those demonstrated until now, going up to the 100 GHz frequency range, introducing numerous advantages, including:

• Higher operating temperature, resulting with more qubits per fridge,

• • Smaller size decreases wafer sensitivity to cosmic radiation.
    Once successful, our approach will open a new, game changing, way to build superconducting quantum computers. Along the way we are facing novel engineering challenges as well as basic material-science questions.
    Due to the increased qubit energy level separation, millimeter-wave quantum processors could be operated at temperatures much higher than their present counterparts, qubit logic gates can be performed faster and circuit components reduced in size thus allowing for a smaller footprint, denser packaging and better integration. These numerous potential advantages face many challenges and pose intriguing physics questions that are aimed to be answered in this project. Once successful, our approach will open a new way to build superconducting quantum computers.
    The group led by Prof. Alexey Ustinov is located at the university campus of KIT and has a long successful record of exploring the physics of superconducting circuits, both classical and quantum. We are using superconducting qubits for state-of-the-art experiments, challenge new physics questions and explore opportunities for the next generation of quantum information processing. Our group pioneered frequency domain multiplexing readout of qubits, detection and manipulation of microscopic two-level defects, and studied qubit arrays as quantum metamaterials. Our labs are equipped with 6 dilution refrigerators and microwave and mm-wave measurement facilities. We have full access to the in-house cleanroom located next to the lab at Nanostructure Service Laboratory / KIT.
    The multiple offered PhD and postdoc positions cover a broad range of directions within Milli-Q project, ranging from the development of cryogenic measurements for mm-wave frequencies to the fabrication of prototype mm-wave qubits and studies of their quantum coherence properties. Our project team will closely cooperate with mm-wave experts and high-frequency electrical engineers, both on and outside the KIT campus.
    This research center is part of the Helmholtz Association of German Research Centers. With more than 42,000 employees and an annual budget of over € 5 billion, the Helmholtz Association is Germany’s largest scientific organisation.
