Postdoctoral Researcher in Quantum Information Theory of Bosonic Systems

About the role

Telecom SudParis, a public engineering graduate school within the Institut Mines-Télécom, is recruiting a postdoctoral researcher for a fixed-term contract of 24 months in theoretical quantum information, with a focus on bosonic quantum systems. The position is based in Palaiseau, Île-de-France, with hybrid work possible.

Key responsibilities

• Research theoretical quantum information, investigating the mathematical and information-theoretic properties of bosonic quantum states and channels, especially non-Gaussian systems
• Study and prove quantum entropic inequalities involving beam splitters and other bosonic transformations, and develop new mathematical tools using quantum information, matrix and operator analysis and majorization
• Apply these results to characterize information transmission through bosonic channels, deriving capacity formulas and bounds
• Teach exercise and tutorial sessions for a quantum information course, prepare exercises and solutions, and supervise student projects and research internships
• Support PhD students and junior researchers, publish in peer-reviewed journals and present at international conferences
• Take part in departmental seminars, project meetings and scientific collaborations

Required profile

• PhD in physics, mathematics, computer science, engineering or a related field
• Research experience in theoretical quantum information, mathematical physics, quantum communication theory or theoretical quantum optics
• Experience with analytical and mathematical approaches to quantum information problems
• Strong scientific background in theoretical quantum information and excellent scientific communication and writing skills

Required skills

• Quantum mechanics and quantum information theory
• Quantum channels, quantum entropies and information-theoretic methods
• Knowledge of quantum bosonic systems
• Advantageous: majorization theory, matrix inequalities, non-Gaussian quantum information, quantum Shannon theory, and tools such as Python, Mathematica or MATLAB

What we offer

• Indicative salary of 35,400 to 38,000 euros gross per year, depending on profile and experience
• Hybrid work, on-site restaurant and cafeteria, public transport access and staff and sports associations on campus

To apply, submit a CV and a cover letter by the deadline of 16 October 2026, including the contact details of two referees.
