Health Sciences

The Faculty of Health Sciences teaches the 3 cycles of medical studies: from PASS (integrated into the faculty) to the 3rd cycle including DES, DESC, DU and DIU. The lessons are given mainly on two sites: Pitié-Salpêtrière and Saint-Antoine. The faculty also provides paramedical education: speech therapy, psychomotricity and orthoptics. The Saint-Antoine site includes a midwifery school.

Master of Computer Science - Quantum Information (QI)

Sorbonne University is offering a master program fully dedicated to Quantum Information in Paris. This program is supported by the Quantum Information Center Sorbonne (QICS), the Computer Science Master Department, in collaboration with the Physics Master Department. Experts from LIP6, LKB and INRIA are teaching recent research results in quantum algorithmics, quantum cryptography, photonic quantum computing and quantum information theory.

This program opened in 2021 and is taught in English for an international student audience. It provides the master's degree in Computing Science with a specialization in Quantum Computing for graduate students in computer science with a strong interest in physics.

Master of Computer Science - Quantum Information (QI)


Who can apply to the M1: Licence/Bachelor’s holders in Computer Science, Computer Engineering or Mathematics. Students should have competences in mathematics and theoretical foundations of computer science, and a strong interest in physics. Knowledge of quantum physics is not required for the M1, as it is taught during the program. However, prospective students should be comfortable with linear algebra.

Bachelor’s holders in Physics with a strong background in Computer Science are also welcome, but we rather recommend the physics Master programs (The international Paris Physics Master and the Master Physique Fondamentale et Applications/profil Information Quantique) of Sorbonne Université, which both lead to our twin M2 program in the physics department, with which we share our quantum information courses.

Who can apply to the M2: M1 holders in Computer Science, Computer Engineering or Mathematics. Students should already have basic knowledge of quantum information. Knowledge of quantum physics is absolutely required for the M2

M1 holders in Physics with a strong background in Computer Science are also welcome, but we recommend our twin M2 program in the physics department, with which we share our quantum information courses.
