The Physical Institute (PHI) is looking from 1. Oktober 2022 and limited to 3 year in full time for
3 PhD Student Researchers in
Superconducting Qubits
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. 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 experiments with 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 of KIT
The multiple offered postdoctoral positions focus on most relevant directions within Milli-Q project, in particular cryogenic measurements at mm-wave frequencies and development 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.
Personal qualification:

A master degree in experimental physics
Good command of English
Strong ambition towards excellence in science and technology at the highest international level is expected
Experience on superconducting circuit design, modeling, and/or fabrication is highly appreciated

We offer you an attractive and modern workplace with access to the excellent equipment of the KIT, a varied work, a wide range of training opportunities, flexible working time models, an allowance for the job ticket BW and a casino/cafeteria.
We prefer to balance the number of employees (f/m/d). Therefore we kindly ask female applicants to apply for this job.
Recognized severely disabled persons will be preferred if they are equally qualified.
Karlsruhe is a mid-sized town located at the northern edge of the Black Forest Area in south-west Germany near the border with France. The town is known for its mild climate due to its location in the Rhine valley. As the third-largest city in the state of Baden-Wuerttemberg, it offers diverse sports and leisure activities, plenty of green space and various cultural institutions. Karlsruhe has won the award "Most Bicycle Friendly City of Germany" so that no car or public transport is usually necessary. The surrounding region is inviting to hikes or bike tours in the Black Forest or the nearby Palatinate and Vosges mountain area in France.
For further information contact Prof. Alexey Ustinov () or Dr. Hannes Rotzinger ().
To apply for the position, please submit your application via e-mail addresses given above as one single PDF document, which should include letter of motivation (no more than one page), CV (indicating your contact information, work history, list of publications, knowledge areas of physics and engineering, experimental skills, language skills, university degrees and grades, honors and awards), and two letters of recommendation or contact details of two possible referees.
Your personal data will be processed by KIT in accordance with this privacy policy.
