We are an interdisciplinary research programme group at the Jožef Stefan Institute and at the Faculty of Mathematics and Physics of the University of Ljubljana, composed of several independent research laboratories spanning multiple topics and disciplines. We study the fundamental quantum phenomena that form the scientific basis of quantum technologies (QT). We investigate quantum-enhanced devices and their applications in quantum computing, quantum simulations, quantum communication, and quantum metrology. We explore applications of QT to other research disciplines (materials, computer science, chemistry, electronics, biology) and make use of artificial intelligence methods. We serve as a national hub for the field of QT and we are also active in outreach and education activities on the topic of QT.
We are looking for passionate new PhD students, Postdocs, and Master students to join the team (more info) !
Read more about quantum technology on the EU Quantum Flagship web portal and on the Wikipedia (also in Slovenian language). For a more in-depth review of the state-of-the-art, consult the ebook “Understanding Quantum Technologies” written by Olivier Ezratty (freely downloadable PDF, 1132 pages, last update in January 2023).
Feeling stressed out? Play a quantum game “Quantum Flytrap”! Or build your own quantum optics experiment. (Both work in a web browser)
We are grateful for funding from the Slovenian Research and Innovation Agency (ARIS), the EU and RRF/NOO.

4. November 2026
Group member Jaka Vodeb co-organized the INQA 2026 conference on quantum simulation and continuous-time quantum computation in Bled, Slovenia (2–4 November 2026), bringing together the international research community. Conference website.
15. June 2026
UL FMF and the Jožef Stefan Institute joined their SiQUID partners at the project’s closing conference to present the results of Slovenia’s quantum communication infrastructure demonstration. Results included a test network for quantum key distribution (QKD) and optical links for end users. Read the report.
1. March 2026
The ARIS-funded QSim-NPQ project (J1-70063), led by Jaka Vodeb, has begun. Running from 1 March 2026 to 28 February 2029, it combines quantum annealers, Rydberg-atom arrays, and numerical methods to study false-vacuum decay, correlated quantum matter, and symmetry-breaking dynamics. Project website.
