International Conference of Quantum Communication and Security (ICQCS) & QSI Conference

International Conference of Quantum Communication and Security (ICQCS) & QSI Conference

The QSI Conference will be held in the center of Paris from 16 to 20 March 2026. This event is a joint initiative of the MSCA project QSI and the QuanTiP research network on quantum technologies, and will serve as the final network conference of the QSI project. The programme will feature high-quality, pedagogical keynote-tutorial and invited talks covering topics such as post-quantum cryptography, experimental and theoretical quantum key distribution (QKD), quantum cryptography beyond QKD, and quantum networks.

As the QSI project reaches its end, the doctoral candidates will jointly organize the conference and present their research through extended talks, alongside invited external plenary speakers. The event will be open to researchers beyond the network. It will also provide valuable training in scientific conference organization and ensuring alignment with the project’s dissemination and exploitation strategy.
