QC2I is a computing project supported by IN2P3, the French national nuclear and particle physics institute. Its goal is to explore the possible applications of the emerging quantum computing technologies to particles and nuclear physics problems as well as astrophysics. The main tasks are:

• to identify, within IN2P3, scientists/engineers/technicians who are interested in using quantum technologies,
• to facilitate the access and training on quantum computers,
• to identify milestones applications for nuclear/particle physics and astrophysics,
• to design dedicated algorithms and proof of principle applications.

The project action has three main directions: Prepare the Quantum Computing Revolution (PQCR), Quantum Machine Learning (QML), Complex Quantum Systems Simulation (CQSS, until end of 2022)
