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.

We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

This project is situated within the context of an innovation of the biology curriculum in Dutch secondary schools. The main purposes are (1) to clarify the relation between teachers’ practical knowledge and the decisions they make when planning and implementing their lessons and (2) to develop a professional…

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.’

Two black holes, in close orbit around each other. Have they slowly drifted together, or did they emerge from two orbiting stars? Together with to colleagues form Amsterdam, Leiden astronomer Simon Portegies Zwart calculated that the second scenario is rather likely.

Quantum computers are a proposed fundamentally new type of computer. They aim to perform some computations much faster than previously possible by exploiting phenomena at the quantum scale, called superposition and entanglement.

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.

The worldwide race to the quantum computer is in full swing. This computer can bring about a breakthrough in discovering medicines and new materials. Leiden researchers, together with the TU Delft, are taking part in the race. There is now a dossier online about their work.

American physicist and quantum computing pioneer Seth Lloyd is the 65th Lorentz professor. He will deliver the Ehrenfest lecture on 5 June, and several more lectures on quantum computing on 11, 18 and 25 June.

Leiden University and the Beijing Institute of Technology will be collaborating in the area of computer science teaching and research. One of the first outcomes of this collaboration will be a joint four-year bachelor's programme. Willem te Beest, Vice-President of the Executive Board, and Professor…

In this thesis, topics relating to the optimization of high-throughput pipelines used for imaging are discussed. In particular, different levels of implementation, i.e., conceptual, software, and hardware, are discussed and the thesis outlines how advances on each level need to be made to make gains…

An international committee has assessed computer science research at all Dutch universities in the period 2009-2014. For its computer science research, Leiden was awarded the ‘highest’ mark (1) for relevance to society.

Contribute to shaping the content and methods of future computer science education. That is what researchers hope to achieve with the Digital Transformation Research project. The Swiss National Science Foundation awarded 544,000 euros to this four-year project in December. The project will map the ideas…

Seven bachelor students in Computer Science at Leiden University are participating in a research project on big data and event management. Their work should eventually result in a system that can be applied at the finish of the Volvo Ocean Race in The Hague in June next year.

How correct are mathematical theorems? And is all the theory around them correct? To find out, mathematics student Dominique Lawson converted a mathematical theorem into computer language. ‘This allows a computer to understand the theorem and check whether the proof behind it is entirely correct.’ The…

The design process of new buildings is extremely complex due to strict requirements. Computer models are used to create the designs. Scientists from LIACS developed advanced algorithms that help their colleagues at Eindhoven University of Technology to optimise these models.

A night sky of more than 40 petabytes in size, simulating young star clusters and understanding how the body inhibits viruses: three Leiden projects have received computing time on one of the national computer systems.

Quantum hardware comes with a different computing paradigm and new ways to tackle applications. Much effort has to be put into understanding how to leverage this technology to give real-world advantages in areas of interest for industries such as combinatorial optimization or machine learning.

Why should you talk to your computer? When children start learning how to read, they do so by using their voice and speaking the words out loud. In this lecture for the University of the Netherlands, Felienne Hermans (Leiden University) explains how speaking a computer code out loud can help children…

Students of the Science Faculty of Leiden University have chosen Frank Takes, researcher and teacher at the Leiden Institute of Advanced Computer Science, to be the Teacher of the Year. Impressively enough, Takes also became the runner up Discoverer of the Year.

Uncertainty and noise are frequently-encountered obstacles in real-world applications of numerical optimization. The practice of optimization that deals with uncertainties and noise is commonly referred to as robust optimization.

Leiden prof. emeritus Grzegorz Rozenberg is honoured with the first life time award in formal languages, a research area of theoretical computer science. During a small ceremony at his house, he received a statue that was specially made for the occasion.

Professor emeritus of Animal Behaviour Carel ten Cate is awarded honorary membership by the Dutch Society for Behavioural Biology (NVG). He received the honour for his activities for the Society and the discipline of behavioural biology.
