Recently, Evert Jan van Leeuwen was able to identify an “unknown” manuscript leaf in the William Godwin Papers of the Abinger Collection at the Bodleian Library (Oxford), while sitting at his desk in Van Eyckhof 4 (Leiden).

Cambridge University Press has published a new book co-authored by researchers from Leiden University, offering both an introduction to machine learning and deep neural networks, and an overview of their applications in quantum physics and chemistry — from reinforcement learning for controlling quantum…

Haunted Europe offers a comprehensive account of the British and Irish fascination with a Gothic vision of continental Europe, tracing its effect on British intellectual life from the birth of the Gothic novel, to the eve of Brexit, and the symbolic recalibration of the UK’s relationship to mainland…

This thesis probes under what conditions quantum computing presents an advantage over classical computing.

PhD defence

Evert Jan van Leeuwen’s entry in Auteur Press’s Devil's Advocate series provides a complete study of the aesthetic appeal of Roger Corman's influential first Poe picture House of Usher.

Exploring the application of game-theoretic frameworks to quantum physics, this study creates novel AI training methods for the precise control of quantum systems.

This project incorporates spatiality into the discussion of medieval demography, allowing for a more nuanced view on medieval town populations. It establishes a maximum population count for towns for periods prior to 1400 and provides a means to compare the ranking of towns using size and density instead…

How can a CLIL approach, with a focus on disciplinary literacies, improve the teaching of the LLA programme’s literary component in senior bilingual education (TTO)?

In the Netherlands, as elsewhere in the world, many patients who are in a palliative care trajectory prefer not to receive full or explicit medical information. This is more often the case for patients with ethnic or cultural minority backgrounds. As open-information provision is the norm, non-disclosure…

Pushing the boundaries of quantum theories – that’s exactly what the physicists at Leiden University excel at. Researchers in Leiden are launching eight new quantum research projects as part of the Quantum Limits consortium.

In 2025 hebben medewerkers en studenten van de Universiteit Leiden veel mooie prijzen ontvangen en belangrijke onderzoekssubsidies binnengehaald.

Leading computer scientists from a variety of fields share their expertise and insights. Dive into the minds of these researchers and learn about real-world applications, the future of AI and related technologies and cutting-edge research. From chatbots to cybersecurity, from quantum to children's stories,…

Museum De Lakenhal issued an open call for creative solutions to the problem of growth addiction. From over 500 submissions, they selected 15 artworks for the exhibition 'If things grow wrong'. These include the creations of Leiden researchers Peter van der Putten and Evert Jan van Leeuwen.

In a recent Physics World podcast, PhD candidate Felix Frohnert from Leiden University explains how his team uncovered hidden connections in scientific literature by using machine learning routines. With this information, it’s possible to predict promising new research ideas in quantum physics. Listen…

The activities of the Europa Institute (also known as the Department of European Law) are supported by ‘Stichting Europees Instituut’. This foundation was the first of its kind in both the Netherlands and Europe as a whole. Established in 1957, its aim was to ‘support and advance the study of scientific…

Computers are capable of making incredibly accurate predictions on the basis of machine learning. In other words, these computers can learn without intervention once they have been pre-programmed by humans. At LIACS, we explore and push the borders of what a revolutionary new generation of algorithms…

A cultural delegation from Taiwan has presented 175 books and journals to Leiden University. The gift is meant as thanks for all the research carried out by the university on the subject of the indigenous peoples of Formosa, as Taiwan was called in the past.

Quantum games aren’t just a fun way to explain quantum physics — they may also unlock new discoveries. According to physicist Evert van Nieuwenburg, these games create structure and clear rules. Simply playing them can even contribute to better quantum software.

Royal honour for Prof. Barend Mons. He was made a Knight in the Order of the Dutch Lion. He received this award from the mayor of the municipality of Waddinxveen, Evert Jan Nieuwenhuis.

In 2024, many of our students and staff won great prizes and secured important research grants.

On Tuesday 12 April Angus Mol and Aris Politopoulos have been awarded the fourth LUCAS Publieksprijs.

Markus Davidsen, assistant professor of Religious Studies, is the winner of the 2021 Impact Prize. He is receiving the prize of 1,000 euros for the material he has developed for religious education in secondary schools.

Who doesn't love to turn on a horror film on a rainy evening? Fortunately, it is only fiction - or is it? According to university lecturer Evert Jan van Leeuwen, modern horror says more about our society than we think. He has been nominated for the Klokhuis Science Prize for his research into addiction…

The Night of Discoveries will take place on 20 September in the area around Hortus botanicus Leiden, the Old Observatory, Pieterkserk, the Academy Building, Old School, the Faculty Club and the PJ Veth Building.
