In cryptography, the sky is the limit according to the new professor Mathematical Cryptology Léo Ducas. He already designed several cryptosystems as part of his research at the Centrum Wiskunde & Informatica (CWI), some of which might soon be adopted as new international standards. Since December,…

On 27 November 2015 Prof. Dr. Grzegorz Rozenberg receives his sixth Honorary Doctorate.

Research groups in the Quantum Matter & Optics programme investigate electronic properties of matter and light-matter interactions with emphasis on quantum information.

On Monday June 15 Prof. Dr. Grzegorz Rozenberg received his fifth Honorary Doctorate.

Human language is constantly evolving with its linguistic structure being shaped by language users at both individual and population levels. Focusing on the interplay between processes of language acquisition and communicative need in shaping human languages, this thesis introduces a novel computational…

Students of the Leiden University master Computer Science are the first students in the world that have been educated in programming with a quantum computer. ‘With this system, it is finally possible to solve complex real-life problems of society.‘

Bernard van Heck has won the Christiaan Huygens Prize 2016 for his Leiden PhD research on electrical circuits for quantum computers. On behalf of the KNAW, the Dutch minister of Education, Culture and Science awards this prize annually to a researcher who has made an innovative contribution to scien…

We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.

In the future, computers will be able to base their decisions on intuition. Professor Jaap van den Herik, director of the Leiden Centre of Data Science, posed this statement today in his Valedictory Address at Tilburg University.

Algorithms solve problems. But which algorithm is best suited to which problem? During his doctoral research, Diederick Vermetten developed methods to figure this out. And that is important for the entire field.

Sonja Boas developed new techniques to study vascular growth computationally. The results of her research provide a better understanding into mechanisms behind vascular growth, which is relevant to the development of medical therapies. She defends her thesis 'Computational modeling of angiogenesis'…

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

‘Rudy van Vliet is always willing to go that extra mile to help us,’ is what students say about him. The lecturer in the Computer Science bachelor’s programme not only teaches his regular courses but also offers additional classes to prepare students for programming competitions. His dedication to students…

Researchers from the Faculty of Humanities and the Faculty of Archaeology, with the support of the communication departments of these Faculties and the VALUE Foundation, has been awarded one of the first NWA-Science Communication and Outreach grant for their plan to produce live-streams via online platform…

Learning a programming language is challenging. Even one of the first –but crucial– concepts to learn, variables, is hard to grasp. Variables can represent different roles and functions within a code and need to be named appropriately to support code comprehension and debugging.

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.

How is Young Star Renske Donkers doing now? Early this year she was the second person ever to win the Young Star Award for the best bachelor student. After her bachelor Molecular Science & Technology, Renske is now busy with her master Chemical Process Engineering in Delft. ‘This award was a great boost…

Breast cancer (BC) is a clinically and biologically heterogeneous disease.

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

Leiden physicists have managed to detect a single molecule called dibenzoterrylene in a new crystal, and found that it is a candidate component for a quantum network. Future quantum computers will need such a network to work together while maintaining their advantages. Publication in ChemPhysChem jo…

Professor Simon Portegies Zwart and doctor Jeroen Bédorf had the honour to write for the IEEE Software magazine.

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…

An international collaboration, including Leiden physicist and computer scientist Vedran Dunjko, showed that quantum technology can speed-up the learning process of artificial intelligence (AI). To prove this, the physicists and computer scientists used a quantum processor for single photons. Their…

Professor Carlo Beenakker has been awarded a FOM Projectruimte subsidy to build a theoretical model of a majorana gun, a very promising instrument for quantum computers.
