Salary: Pay group 13 (75%) TVöD-Bund

Application Deadline: The position will be published until it is successfully filled.

Index number: 2026D-0644

Your Job

• Analyze the intrinsic many-body dynamics of noisy and monitored quantum circuits, mapping them onto statistical-mechanics models
• Develop analytical approaches (e.g. replica methods and exactly solvable models) alongside large-scale numerical simulations on high-performance computing facilities
• Characterize the transitions that govern quantum information protection, from encoding and decoding transitions to error-correction thresholds and emergent fault tolerance
• Exchange with national and international project partners within the quantum networks of Jülich and Cologne
• Present your research results at international conferences and prepare scientific publications

Your Profile

• Master’s degree in physics or a closely related subject
• Solid background in quantum many-body theory and/or statistical physics; expertise in quantum information is particularly appreciated
• Strong programming experience and/or strong background in analytical methods
• Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the CEFR), ideally supported by a certificate confirming the language level
