And the Rotterdam Economics programme was voted the best in its field. Leiden University now offers a combined study based…

With defending his thesis ‘Applications of topology to Weyl semimetals and quantum computing’, the Leiden theoretical physicist Tom O'Brien has gained the rare 'cum laude' qualification. The freshly minted PhD has started a five year research programme on quantum algorithms for quantum chemistry, funded…

There are a number of problems in philosophy that seem to share a similar possible solution: 'Why do promises and contracts bind?', 'Why ought citizens and judges obey the law?' and 'Can we realize the gains to be made from cooperation?'. All three problems (as well as some others) share a possible…

Learning how computers can process and describe images just like human beings do. It is one of the key elements of the research of Michael Lew, who sees Deep Learning as a promising way to achieve this goal. On the 1st of January 2021, he was appointed Professor of Deep Learning at the Leiden Institute…

Striga hermonthica, commonly known as witchweed, infests major cereal crops in Sub-Saharan Africa causing severe yield losses and threatening the livelihood of millions of resource poor farmers.

This thesis introduces the concept of

Media & interaction is where artificial intelligence and machine learning meet philosophy, cognitive science, and the creative arts. Examples of research questions in this domain are: 'Can an algorithm be creative by human standards?', 'Can creative processes, such as composing music or writing poetry,…

Data and information should be stored in a way that computers can understand, says Barend Mons, professor of Biosemantics at the Leiden University Medical Center and Chair of the High Level Expert Group for the European Open Science Cloud. We speak with him about FAIR data, knowlets and nanopublicat…

Computer skills are essential if you want to become part of Dutch society. Leiden University and Stichting Bestaanskracht, an organisation that helps the vulnerable, are therefore providing computer lessons for refugees who can use some extra digital help.

LUGO has some news: If you are using a public computer from Leiden University, you can now set your default search engine to Ecosia.

The fact that scientists are increasingly better able to access molecular cell and tissue data also brings with it a new challenge: how can scientists find the information they need for research among the vast amount of data available?

Media & interaction is where artificial intelligence and machine learning meet philosophy, cognitive science, and the creative arts. Examples of research questions in this domain are: 'Can an algorithm be creative by human standards?', 'Can creative processes, such as composing music or writing poetry,…

The aim of this thesis is to present novel techniques for proving cryptographic schemes secure against quantum adversaries. Most results are within the context of an idealized model called the ‘quantum random-oracle model’.

A collaboration of physicists and chemists organized the LEELIS conference on new computer chip technology in Amsterdam on 10-11 November. Leiden physicist Joost Frenken is director of the organizing institute ARCNL.

A mix of data research, artificial intelligence and archaeology led to lively discussions on 31 January. On that day the unique event 'AI & Data Science @ Archaeology' took place in which the Data Science Research Programme (DSRP), SAILS and the Faculty of Archaeology joined forces.

A piece of corrugated rubber can function as a simple computer, displaying memory and displaying the ability to count to two. Leiden physicists describe the computing rubber in the journal PNAS. ‘Simple materials can process information, and we want to find the principles behind that.’

This thesis deals with the use of sound in interactions in the context of participatory systems and data sonification. We investigate an interactive environment where participants perceive information of the data through sound elements.

With the help of quantum mechanics, digital quantum hardware may be able to tackle some of the problems that are too difficult for ordinary computers. But despite these expectations and the ongoing effort of the research community, reliable quantum computers are not yet realized in a lab setting.
