Physicist Martin van Exter works with light at nanoscale, at the forefront of nanocomputer research. But as Director of Education he also has a vision for physics teaching. Inaugural lecture 18 November.

Most of current public-key cryptography is considered insecure against attacks from sufficiently powerful quantum computers. Post-quantum cryptography studies methods to secure information resistant against such attacks. One proposal is isogeny-based cryptography, which bases its security on computational…

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

Nonparametric Bayes for high-dimensional models: contraction, credible sets, computations

Science, Leiden Institute of Advanced Computer Science (LIACS)

Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

Natural Computing is the field of research that investigates both human-designed computing inspired by nature and computing taking place in nature, i.e., it investigates models and computational techniques inspired by nature and also it investigates phenomena taking place in nature in terms of information…

The zebrafish is a promising vertebrate model organism in early drug discovery and development.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

HEPGAME is a research project that combines the world’s fastest computer algebra system for High Energy Physics equations, FORM, with insights from artificial intelligence. The name combines High Energy Physics and Games.

Can we use quantum computers in a way that is also relevant to society? With the help of a 2-million-euro NWA grant, Leiden University will work with partners such as Surf, Google and Volkswagen to demonstrate that quantum computers are also of value outside the lab.

The 2024 Computers, Privacy and Data Protection (CPDP) conference taking place in Brusselson 22-24 May, featured a presentation from Simona Demkova of the Europa Institute at Leiden University. Simona spoke on a panel that explored the intricate balance between innovation and fundamental rights in the…

On Thursday 18 December, 170 first-year pupils from Gymnasium Haganum visited Leiden University’s Faculty of Governance and Global Affairs (FGGA) in The Hague. The faculty has developed The Great Migration Game (Het grote Migratiespel) as a fun way to introduce pre-university pupils to its fields of…

Infecting each other with viruses and bacteria while protecting yourself with medicines and vaccinations. Sounds like a fun evening, right? Master students Life Science & Technology Rafael Jezior and Dennis de Beeld certainly think so. Together, they developed ImmunoWars: an exciting card game based…

The 18.8 million euro NWO Zwaartekracht grant for quantum software which Amsterdam, Delft and Leiden landed collectively, means for Leiden University among others the appointment of two new permanent scientific staff members, who will each form their own research group, divided among Computer Science,…

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

How do humans control their thoughts and actions, and what can high-field brain scanning reveal about the underlying processes?

This dissertation shows that dialogical logic constitutes a powerful and flexible general framework for the development and study of various logical formalisms and combinations thereof.

The Bachelor Honours Class 'Homo Ludens: Why We Play' combines games, theory, and practice. Students dive into all aspects of humanity in which games play a part and discuss them, both on a theoretical an experiential level: 'Occasionally, you touch upon what play is, but then it eludes you.'

If computers work on superconducting current, they won’t consume any energy. Leiden physicists have now gained control over a new type of superconducting memory elements. Publication in Nature Communications.

Not many scientists can claim to have received funding from NWO to blow bubbles and play with sand, but Martin van Hecke definitely can. Van Hecke, Professor of the Organisation of Disordered Matter, delivered his inaugural lecture on Friday 4 September, under the enigmatic title of: ‘Bellen, bollen,…

The quantum computer is on its way, but is society ready for it? Quantum computers have a reputation of being difficult to grasp because of their complexity. This limits society’s ability to envision future applications creating a gap between society and quantum computers. A consortium of 14 knowledge…

In this project, we aim to obtain a quantitative understanding of the role of the immune system in tumor regression, of the role of tumor cell heterogeneity in cancer growth and of tumor cell migration properties.

Three Leiden students will be sharing their knowledge of history while playing video games. The livestreams are part of the ‘Streaming the Past’ project and will be available on the popular streaming platform Twitch. The first livestream will be on Thursday 20 May.

Programming courses are often only available in English. All the more reason for the Programming Education Research Lab (PERL) of the Leiden Institute of Advanced Computer Science (LIACS), Eindhoven University of Technology and University of Twente to translate the 'Beauty and Joy of Computing' programming…

Leiden physicist Julia Cramer receives 50 thousand euros in funding for 'Let's talk about quantum', a research project on communication about quantum computing. A project for high school students by education expert Henk Buisman is also included in the NEWA ELSA funding.

Morning yoga, having your resumé checked at the information market, or dancing for inclusiveness: just a small selection of the activities of the first Science PhD Day on Thursday 18 April. Around 120 PhD candidates from all eight institutes of our faculty attended the day. 'A great success', according…

The standard approach to build a quantum computer with Majoranas as building blocks is to convert them into qubits. However, a promising application of quantum computing—quantum chemistry—would require these qubits to be converted again into so-called fermions. Physicists from Leiden and Delft suggest…
