Doctoral Thesis with Innsbruck University: Trapped-Ion Quantum Processor Development (f/m/div)

Get the best of both worlds with an industrial doctorate at Infineon: Pursue a doctoral degree at a university and gain professional experience simultaneously - an ideal start for your career. Advance your research with us and profit from our vast network of doctoral candidates and the expertise of a university. Mentorship is handled by both professors and dedicated Infineon experts.

We are offering a doctoral thesis in the field of trapped-ion quantum computing. As part of our growing ion trap systems team, you will develop trapped-ion quantum processing units. In particular, your technology development work will focus on ion traps on structured glass substrate, which is a preferred material for academic research groups due to its ease of use in their experiments. However, glass substrates are a non-standard substrate material in CMOS fabs and therefore require adaptations to process routes and fabrication process parameters.

You will design your ion traps specifically for the quantum information experiments at Innsbruck University, then initiate and support ion trap fabrication at our industrial fabrication facilities in Villach. Our project partner Joanneum Research will provide essential glass-structuring expertise to enable new topologies for quantum information processing with academic chip traps.

After successful chip fabrication, you will employ your devices for quantum information processing experiments at the world-leading quantum optics laboratory at Innsbruck University. Your thesis will accelerate technology development of scalable trapped-ion quantum processors and therefore provide a substantial boost towards useful applications with economic impact.

The thesis will be written in cooperation with our academic partner at Innsbruck University and you will spend a total of 3 semesters in Innsbruck for lectures, trainings and trapped-ion experiments with your own quantum processors.

In the course of the thesis you will:

• Develop scaling elements for ion traps on structured glass substrate, like optical access, shuttling elements, junctions and islands electrodes
• Conduct ion trap fabrication by defining a fabrication route, find solutions to process restrictions and implement measures to improve fabrication yield
• Investigate strategies to mitigate scaling blockers like RF-capacity, dielectric losses, cross-talk or ohmic losses
• Test your ion traps at the Infineon quantum lab
• Conduct research at our academic partner Innsbruck University, with ca. 3 semesters dedicated on-site in Innsbruck
• Support the quality and reliability of Infineon ion traps by defining control concepts for inline process control, device screening and component verification

Start: 01.07.2024 (or later)

Full-time employment: 38.5 hrs/week

Duration: 3 yearsA doctoral student is a research enthusiast,

• …whose interests are scientific research combined with the passion for Infineon's innovative products and applications
• …who enjoys working in an industrial environment in combination with an Infineon partner university
• …who appreciates open communication and the contribution of an international environment
• …and is thus an excellent candidate for a further academic or industrial career after completion of their thesis

As the ideal candidate you:

• are a highly motivated individual who wants quantum computing to become a reality
• have a master's degree in physics, quantum engineering or similar
• have gained first experience in semiconductor manufacturing or ion trap fabrication
• are fluent in English and German
