Internationally recognized laboratories
The Fundamental Computer Science Research Institute (IRIF), Materials and Quantum Phenomena (MPQ) and the Virgo/Einstein group of the laboratory AstroParticule et Cosmologie (APC) research units lie at the heart of Université Paris Cité’s expertise in quantum information. They span computer science, fundamental physics, and the development of innovative quantum technologies, and enjoy worldwide recognition for their research.
Université Paris Cité also has staff based in off-site laboratories, in particular at the Physics Laboratory of the École Normale Supérieure, as well as at the Center for Nanoscience and Nanotechnology.
A unique transdisciplinary approach
Research at Université Paris Cité brings together multiple disciplines in an original and integrated way:
-
Computer science: development of quantum algorithms and analysis of their limitations
-
Theoretical physics: study of physical systems used as carriers of quantum information
-
Experimental physics: implementation and manipulation of qubits, and their use in applications
This cross-disciplinary approach connects theory and experimentation while fostering scientific innovation.
A historical and philosophical perspective
The Sciences, Philosophy and History (SPHERE) research unit brings a complementary dimension by examining the historical and philosophical evolution of practices of measurement and knowledge. Its work deepens the understanding of conceptual, epistemic, material, and institutional issues, offering a comprehensive view of the quantum sciences—particularly quantum optics—beyond purely technical aspects.

Quantum Computing and Quantum Physics Explained Differently
Quantum computing and quantum physics are now major scientific disciplines, but they remain complex to understand. To make them more accessible to non-expert audiences, Sophie Laplante, Associate Professor in algorithms and quantum and classical computational complexity at IRIF, the Fundamental Computer Science Research Institute (Université Paris Cité/CNRS), and appointed Senior Member of the Institut Universitaire de France (IUF) in 2025 under the Science Communication Chair, designs educational tools.
