Postdoctoral Researcher in Quantum Algorithms

The mission of the Institute for Quantum Computing Analytics

(PGI-12) is to model and improve quantum computing systems on multiple levels. From optimal control of the hardware, over error mitigation and compilation, to application specific quantum algorithms. We focus working on interfaces between disciplines in large innovative projects that strive for the development of scalable and useful quantum computers. In a tight integration with quantum computer hardware developers, we investigate the applicability of quantum computers towards real-world applications in a hardware-software co-design paradigm.

Your Job

Within an interdisciplinary research project, you will develop and analyze quantum algorithms, demonstrating and systematically evaluating their applicability on quantum computers. Financial risk modeling serves as a concrete application domain; however, the algorithmic research is the primary focus.

Design, implementation, and evaluation of quantum algorithms for risk assessment, based in particular on Quantum Amplitude Estimation (QAE) and related phase and amplitude estimation methods, including variational approaches
Development and analysis of efficient oracle implementations for quantum algorithms, particularly for the input and output of classical data (block encodings, QRAM architectures, data upload procedures), to realize end-to-end quantum speedup
Investigation and testing of adiabatic and gate-based optimization algorithms for combinatorial optimization problems, using portfolio optimization as a representative example
Systematic benchmarking of the developed methods on available quantum hardware and hybrid QC-HPC infrastructures using emulators; evaluation of scalability, resource efficiency, and stability compared to classical HPC methods
Assessment of quantum-computing-specific constraints such as circuit depth, gate fidelity, and hardware-related limitations regarding achievable quantum advantage
Creation of modular, reusable algorithm libraries and reference implementations
Leading contributions to scientific publications and conference presentations
Supervision of doctoral and master’s theses

Your Profile

Doctoral degree in Physics, Computer Science, Mathematics, or a comparable field
Proven research experience in quantum algorithms and/or quantum information theory
In-depth knowledge of quantum algorithms (ideally Quantum Amplitude Estimation or related approaches, as well as oracle implementation)
Solid understanding of quantum complexity-theoretic foundations (circuit complexity, oracle models, speedup guarantees)
Experience in implementing quantum algorithms on real quantum computing systems or high-quality simulators
Ability to work independently and in interdisciplinary teams
Strong organizational and communication skills
Ideally, experience in software development
Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the ), ideally supported by a certificate confirming the language level. Knowledge of the German language is not mandatory but certainly appreciated
