Felix Leditzky

Felix Leditzky is an Assistant Professor in the Department of Mathematics at the University of Illinois Urbana-Champaign, holding the Lincoln Excellence for Assistant Professor (LEAP) Scholar position in the College of Liberal Arts & Sciences. He is a member of the Illinois Quantum Information Science and Technology Center (IQUIST) and was previously a David Blackwell Scholar (2023-2025). In 2025, he received an NSF CAREER grant for research on symmetries in noisy multipartite quantum systems.

His research centers on mathematical and information-theoretic aspects of quantum information theory, with specific interests in quantum channel capacities, superadditivity phenomena, quantum source coding, data processing inequalities, strong converse theorems, second-order asymptotics, group theory applications, representation theory, matrix analysis, and many-body quantum systems. His work bridges theoretical mathematics with practical quantum information processing challenges.

Leditzky's recent publications demonstrate strong focus on quantum communication protocols (teleportation/dense coding duality), entanglement characterization through topological methods, unitary designs for quantum computing, and fundamental limits of quantum channel capacities. His research consistently applies advanced mathematical techniques to solve concrete problems in quantum information science, with increasing emphasis on multipartite systems and networked quantum communication.

• NSF CAREER grant (2025)
• Lincoln Excellence for Assistant Professor (LEAP) Scholar
• David Blackwell Scholar (2023-2025)
• Editor at Quantum journal (quantum information theory)
• Editorial board member of Illinois Journal of Mathematics

As principal investigator of the Leditzky Research Group, he mentors a diverse team of postdocs, graduate students, and undergraduates across Mathematics, Physics, ECE, and Computer Science departments. His group has secured significant funding including NSF CAREER and IQUIST postdoctoral fellowships. Leditzky actively organizes major conferences including TQC 2022 and QIP 2019, and serves on program committees for QIP and other leading quantum information conferences.

The Leditzky Research Group operates at the intersection of mathematics and quantum information science, maintaining strong collaborations across departments and institutions. Their work combines theoretical rigor with computational approaches, frequently employing semidefinite programming, representation theory, and topological data analysis to tackle fundamental problems in quantum communication and information processing.
