# PhD position for qFLOWproject

Limited: 3 years | Starting date: earliest possible | ID: APDO004/2026 | Deadline: 31.07.2026 | Full-time/Part-time | Remote work possible

DESY, with more than 2900 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.

The Centre for Quantum Technology and Applications (CQTA) at DESY’s Zeuthen site focuses on applied research in quantum computing and quantum sensing. Its core mission is to identify and develop use cases for these technologies in science and beyond. This position is part of the qFLOW project, which investigates the potential of quantum computing for simulating complex fluid flows. Such systems are governed by nonlinear, multiscale partial differential equations (PDEs) and play a key role in fields such as hydrology, environmental science, and energy technology. Despite their importance, accurately simulating these phenomena remains computationally demanding and, in many realistic scenarios, beyond the reach of even state-of-the-art high-performance computing (HPC) systems.

## About your role:

- Development of quantum algorithms for fluid dynamics problems
- Development of quantum Lagrangian Neural Nets for Droplet and Bubble Interface Oscillations
- Implementation and benchmarking on quantum hardware and classical simulators
- Publication of the scientific results in journals and presentation at conferences/consort

## About you:

- PhD physics with focus on quantum computing and quantum information
- Strong background in numerical simulations and knowledge in some (high-level) programming language, e.g., Python, Julia, C++
- Experience with Qiskit, the ITensor framework or other Tensor Network packages is an advantage
- Basic knowledge of machine learning and/or fluid dynamics is an advantage
- Good command of written and spoken English
- Excellent teamwork ability
