The QuanTour team, led by Professor Doris Reiter and Professor Tobias Heindel, in collaboration with Dr Pranoti Kshirsagar, has made a transformative contribution to the public understanding of quantum science, particularly in the UK and Ireland. Through the ambitious QuanTour initiative, the team demonstrated the technical feat of transporting and operating a quantum dot light source across 12 laboratories in 12 European countries over 12 months. This extraordinary effort highlighted the collaborative nature of physics research and the challenges of implementing advanced quantum technologies in diverse environments. At the heart of QuanTour is the quantum dot light source, a cutting-edge device capable of emitting single photons on demand, fabricated by Dr Lucas Rickert at TU Berlin. This is achieved through quantum dots, tiny semiconductor structures that confine electrons, allowing precise control over photon emission. The single-photon nature of the source is confirmed through a Hanbury Brown and Twiss measurement, which uses two detectors to verify that photons are emitted one at a time. Single-photon sources are critical for secure quantum communication and scalable quantum computing, making this technology a cornerstone of the rapidly advancing quantum revolution. The project had a profound impact on public engagement with quantum science in the UK, collaborating with key figures such as Professor Mete Atatüre (University of Cambridge, Cambridge, UK), Professor Brian Gerardot (Heriot-Watt University, Edinburgh, UK) and Professor Emanuele Pelucchi (Tyndall National Institute, Cork, Ireland). QuanTour delivered engaging content, in particular digital spaces, to spark curiosity and deepen understanding of quantum technologies. These activities aligned with the International Year of Quantum Science and Technology 2025, amplifying their relevance as quantum science captures global attention. QuanTour’s innovative approach combined laboratory demonstrations with multimedia outreach. Podcasts created with The Science Talk featured the organisers and laboratory leaders, offering unique insights into the careers, challenges and triumphs of physicists. These stories brought quantum science to life, inspiring students, educators and the general public to engage with cutting-edge research and its real-world potential. By demystifying quantum technologies and emphasising their importance for the future, QuanTour has strengthened the connection between the scientific community and society. This is especially vital as quantum technologies transition from the lab to real-world applications.
