The Quantum Information Theory group led by Prof. Michael Walter at LMU Munich is inviting applications for several PhD and postdoctoral positions. We are looking for excellent and highly motivated candidates in all areas of the field, including: quantum algorithms and complexity, quantum information theory, quantum cryptography, quantum information in many-body physics and space-time, quantum programming languages and formal methods, mathematical and computer science foundations and connections.
For more information about the positions and how to apply, please see: https://michaelwalter.info/jobs
In Munich, you can expect an excellent research environment in quantum information science, with the Munich Quantum Center, the Munich Quantum Valley, and the Cluster of Excellence Munich Center for Quantum Science and Technology, forming one of the world's leading hubs for quantum research, with many activities to participate in.
Applications will be reviewed on a rolling basis until the positions are filled. The starting date is flexible, but is ideally no later than fall 2026. We look forward to receiving your application!

\opening{Dear Members of the Search Committee,}
I am writing to apply for a postdoctoral position in Quantum Information Theory group led by Prof. Michael Walter at LMU Munich. I am currently a Ph.D. researcher in the Department of Theoretical Physics at the Tata Institute of Fundamental Research (TIFR), Mumbai, and expect to receive my doctoral degree by August 2026.
My research lies at the interface of quantum information and quantum gravity. In particular, my work focuses on quantum complexity, random matrix theory, and holographic quantum information. I am interested in understanding the role of quantum information–theoretic concepts in gravity, especially in relation to complexity growth, quantum chaos, and the emergence of spacetime geometry from quantum dynamics. I am also open to work in exploring other directions within quantum information theory.
Details of my past research and future research plans can be found in the attached documents. I apologize for the additional PDF containing the professional recommendation letters.
I am also comfortable with scientific programming in Python. Some of the codes related to my recent work on stabilizer complexity can be found here:

\end{center}
I believe that the research environment at LMU Munich would provide an excellent opportunity to pursue these directions at the intersection of quantum gravity and quantum information.
Thank you very much for considering my application.\

\section*{Research Interests}
My research lies at the intersection of quantum information and the AdS-CFT correspondence. I focus on how tools from quantum information theory—such as entanglement, complexity, and quantum error correction—enhance our understanding of the holographic duality between quantum field theories and gravitational systems.
