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,…

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.

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,…

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.

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

How do we know what a quantum computer is good for when it hasn't been built yet? That's what PhD candidate Casper Gyurik investigated by combining two terms you often hear: quantum computing and machine learning.

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…

Our banking, DigiD and sensitive medical data: what if our entire digital infrastructure can no longer be trusted? Jelle Don has this question permanently in mind as he goes about his research. And that is no bad thing because without new digital security measures, our society will be extremely vuln…

During the Bachelor Honours Class ‘The world is quantum’, students from various disciplines learned about the rules of nature on the smallest scale: quantum mechanics. What opportunities and dangers do they see for their field of study?

Physicist Kaveh Lahabi’s research on quantum materials led to the launch of a new company: QuantaMap. With his colleagues, he developed a sensor that will improve the production of quantum computer chips. ‘It turns out that what I need for my fundamental physics research is also very useful for the…

Mass, time, space, and complexity — physicists in Leiden are launching eight new research projects tackling some of the most fundamental themes in quantum mechanics. Their goal: to push the limits of current quantum theories.

Quantum technology, statistics and a survey with memes: definitely not your everyday research. Julia Cramer (Leiden Institute of Physics) and Sanne Willems (Institute of Psychology) investigate how people perceive quantum.

A suitcase covered with stickers from various universities, containing a quantum light source. Since April 2024, this suitcase has been visiting scientists in Europe researching single photons: the smallest possible quantity of light. The suitcase, also called ‘Q-torch’, travels from lab to lab like…

To mark the university’s 450th anniversary, the Leiden Discoveries science route has been updated and was relaunched on the Night of Discoveries. New signs in town and a revamped website tell Leiden residents and visitors the stories of the city’s spectacular discoveries.

In addition to compulsory elements, most degree programmes also have elective credits. These are credits you can earn in a variety of ways, for example by taking elective courses, studying abroad or doing a minor.

Designing innovative algorithms, thinking outside the box, and brainstorming over coffee with his colleagues — this is what physicist Stefano Polla enjoys most. His success shines through in his nomination for the C.J. Kok Jury Award 2024 for PhD thesis of the Year.

‘Quantum technology is going to change the world, but most people don’t feel connected to it. I want to change that,’ says Julia Cramer, assistant professor at Leiden University. Known for her passion for science communication, Cramer actively seeks opportunities to share the wonders of quantum technology…

Besides physics, the sleep of PhD students also benefits from Vitaly Fedoseev's PhD research. He will receive his doctorate on July 7 for his work on optomechanics within quantum mechanics. And also on a setup that eliminated the need for PhD students to push a button every hour for 72 hours.

A suitcase as a messenger of quantum science. That is the idea behind QuanTour, a project connecting researchers from 12 European universities. In December, the suitcase landed in Leiden. A month later, it is time to pass the baton to Copenhagen. But what happened to it in Leiden?

Conference

Quantum Rules lab van Leiden Universiteit biedt proefjes en experimenten voor middelbare scholieren om te leren over kwantum natuurkunde. Henk Buisman vertelt over het 5 jarige jubileum.

Jianfeng Ge and Milan Allen of Leiden University look for majorana quasiparticles using shot noise measurements

A minor allows you to develop your knowledge beyond the boundaries of your study programme, or to specialise further in your own field of study. You can follow a minor in Leiden and also in Delft or Rotterdam.

‘Jelena Prokic, university lecturer and researcher at the Leiden University Centre for Digital Humanities, will be preparing students for the challenges and opportunities of the digital world. In September, six modules will start on subjects such as statistics and digitally searching through texts.…
