PostDoc

The Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences in Innsbruck invites applications for the IQOQI Prize Postdoctoral Fellowship in Quantum Science for the year 2026.

Recipients should show outstanding research in theoretical or experimental quantum physics commensurate with the level of the position, and an ability to identify and pursue research problems independently while working well in an interactive and dynamic setting. They need to have completed their Ph.D. degree by the time they start their assignment.

The postdoc will work on our project coupling single strontium atoms to nanoscale defect cavities with the ultimate goal of creating quantum states of massive mechanical resonators. The position is fully funded for 2 years by my ERC starting grant.

We are seeking a highly motivated postdoctoral researcher with a Ph.D. in Physics (or a related field) to join the Quantum Information and Matter Group led by Prof. Peter P. Orth at Saarland University. Our group is part of the recently established Quantum Technology Center (QuTe) at Saarland University—a dynamic, interdisciplinary research hub uniting expertise in computer science, mathematics, engineering, chemistry, and physics. Through our close partnership with the Helmholtz Forschungszentrum Jülich, we offer unique opportunities for joint projects, networking, and access to cutting-edge HPC and quantum computing resources.

Potential research directions include: Quantum algorithms for simulating many-body systems, quantum field theories, and combinatorial optimization. Implementation and end-to-end resource cost estimation of quantum algorithms on current and near-term early fault-tolerant quantum hardware. Development and application of quantum error mitigation and error correction protocols. Join us to shape the future of quantum!

This fellowship aims to explore the use of quantum computing for Earth observation (EO) applications, potentially in combination with artificial intelligence and high-performance computing (HPC) technologies. In particular, you will apply (hybrid) quantum computing solutions to EO use cases for which current classical computing algorithms are NP-hard or, in general, difficult to implement.

In particular, you will:

The research group of Prof. Bihui Zhu at the Homer L. Dodge Department of Physics and Astronomy and the Center for Quantum Research and Technology at University of Oklahoma in the United States is looking for postdoctoral researchers to join us. The successful candidate will conduct theoretical research focusing on many-body phenomena relevant to near-term quantum platforms. Topics of research include but are not limited to, quantum dynamics, topological phases, and quantum sensing.

For our group at the University of Siegen (Germany) we are looking for a motivated postdoc and/or PhD student in the field of quantum information theory, foundations of quantum theory, and quantum optics. The group is led by five PIs (Otfried Gühne, Matthias Kleinmann, Stefan Nimmrichter, Chau Nguyen and Ramona Wolf) and the research topics include:

At neQxt, our theory team explores the principles that make scalable quantum computing possible. We study how fault tolerance can be realized under realistic conditions, designing circuits, developing simulation methods, and analyzing noise at the circuit level. A key part of our work is to understand trade-offs between different approaches and how they can be embedded into modular architectures. We aim to connect theoretical insights with practical feasibility, developing techniques that move fault tolerance closer to realization. By building tools, models, and architectures, we provide a bridge between abstract principles and the requirements of physical quantum processors.

At neQxt, our theory team explores the principles that make scalable quantum computing possible. We focus on logical-qubit systems: developing quantum error correcting codes, decoding methods, and logical gate constructions, and studying the mathematical structures that underlie them. Our work aims to deepen the understanding of how fragile quantum information can be preserved over long timescales and across large systems. By advancing the theoretical foundations of quantum fault tolerance, we contribute to both the science of quantum information and the long-term vision of reliable quantum computing.
