Expert directory

Find researchers, principal investigators and official contacts in quantum technology with a European affiliation. Every entry is built from public sources and shows professional information only: name, organisation, country, role, topics and works. About this directory, its sources and how to remove or correct an entry

5166 entries found. 5166 entries in the directory, read on 2026-10-28; people are listed with at least 5 quantum works with a European affiliation since 2022.

This directory is incomplete. Its publication threshold can exclude early-career researchers, career breaks and smaller research communities. Absence is not evidence of lack of expertise. Country means institutional affiliation, not nationality.

Suggest your profile or a missing expert for editorial review. Suggestions are reviewed by a person before publication. An EC evaluator label records a sourced past role; it does not confirm current availability or Commission endorsement.
