Application deadline: Wednesday, September 30, 2026 Research group: Center for Theoretical Physics PAS Employer web page: Center for Theoretical Physics PAS, Warsaw, Poland Job type: Other PhD Tags: open quantum systems many-body physics quantum information quantum technologies computational physics tensor networks PhD Position PhD Candidate Openings: Open Quantum Systems & Many-Body Physics The Center for Theoretical Physics PAS (CTP PAS) in Warsaw is seeking two Research Assistants / PhD Candidates (R1 Researchers) to join the EUCENTRAL – Center for Quantum Technologies Modelling project. The research will focus on many-body open quantum systems , combining theoretical physics, numerical methods and computational modelling. The successful candidates will contribute to the development of theoretical and computational tools for quantum technologies. 📍 Warsaw, Poland 👥 2 positions available 💰 PLN 8,000–9,000 gross/month 🧮 Quantum statistical mechanics & many-body theory 💻 Programming & numerical computations 🌐 International and interdisciplinary research environment 📅 Application deadline: 30 September 2026 📆 Starting date: from 1 November 2026 at the earliest ⏳ Duration: 36 months 🔖 Ref.: MSz/23/2026 We are looking for candidates with a Master’s degree in Physics or a related field . Candidates who have not yet formally obtained the degree may also apply, provided they submit documentation confirming the current stage of the degree-awarding process and obtain the degree before the start of employment. Candidates should have a strong background in quantum statistical mechanics and many-body theory , as well as programming skills and experience with numerical computations. Experience with open quantum systems , including master equations and/or quantum stochastic calculus, or alternatively with quantum optimal control or quantum information theory , will be an advantage. Familiarity with numerical tools for many-body quantum systems , such as exact diagonalization or tensor networks, as well as experience with version control and collaborative coding (GitHub) , is also desirable. The selected researchers will work on original research in many-body open quantum systems , developing theoretical and computational tools, participating in international conferences and schools, and contributing to the maintenance of open-source code libraries. 👉 Full details & how to apply: View full job announcement Join the EUCENTRAL project and develop your research career at the intersection of open quantum systems, many-body physics and computational quantum technologies .
