Kirsten Kanneworff and David Dechant defend their PhD research on quantum physics at Leiden University. Fundamental work with applications in location verification and the financial world.

Can you prove whether a large quantum system truly behaves according to the weird and wonderful rules of quantum mechanics — or if it just looks like it does? In a groundbreaking study, physicists from Leiden, Beijing en Hangzhou found the answer to this question.

Are quantum computers the scientific breakthrough of our time? In this podcast, Carlo Beenakker, Professor of Physics at Leiden University, explains quantum technology.

Three quantum-safe cryptography methods have been standardised for worldwide use since this week. Léo Ducas co-designed the two primary PQC methods selected for this standardisation. Ducas is part of the Cryptology group at Centrum Wiskunde & Informatica (CWI) and is also professor of Mathematical cryptology…

The second quantum revolution is in full swing, bringing all kinds of new technologies to within reach, and offering many opportunities as well as challenges. Leiden and Delft decided to join forces.

No less than six Leiden projects received a grant for quantum research from the national growth programme Quantum Delta NL and the NWO. After all, in order to boost quantum technology not only industry is needed, but also science. Research towards new sensors, faster algorithms and quantum materials,…

Europe's latest quantum computer is set to arrive in the Netherlands. The Dutch IT cooperative, SURF, which supports education and research institutions, has secured funding from the European EuroHPC programme to make this possible. Researchers from Leiden University will play a key role in the project,…

Goldband, Skrillex, Róisín Murphy and... quantum: the latter may not be a band but is part of the Lowlands line-up nonetheless. Scientists from Leiden University are using the festival for research on the very smallest particles.

Opening van het Quantum Delta NL (QDNL) Talent & Learning Centre (TLC) Leiden-Delft.

Leiden physicists Carlo Beenakker and Bas Hensen receive 35 million euros in a consortium with researchers from QuTech and Delft University of Technology. They will investigate the fundamental limits of quantum physics.

Assistant Professor Vedran Dunjko and his team receive a €100,000 gift from Google to support them in their quantum research. The research focuses on whether quantum computers can provide new ways of understanding the mysteries of high-energy physics. Google is committed to supporting ambitious research…

Vedran Dunjko appointed to full professor of quantum computing at Leiden University, the Netherlands.
