Top scientists of three Dutch universities are working on software and systems for quantum computers. Researchers of the Leiden Institute of Advanced Computer Science (LIACS) and the Leiden Institute of Physics (LION) are developing new algorithms to make those super computers work. The coming years,…

During the opening of the academic year, true to tradition the LUC Teaching Prize will be awarded to the best lecture at the University. Get to know the nominees. This week: Christine Espin.

The Editorial comment in the June issue of the Common Market Law Review examines three different aspects of the rule of law in relation to the European Union. Despite, or because of, the many challenges facing the Union, these questions are of continuing importance. The Union itself is based on legal…

Providers of telephone, internet or data centers can be seen as companies of vital importance because of their national importance. This comes as no surprise. In the Netherlands, additional legislation was deemed necessary to protect national security and a legislative proposal was presented in April…

My research project aims to analyze reasons of the European Union’s (EU) inadequacy to develop a strong Common Security and Defense Policy (CSDP) with regard to the role of main EU member states, namely Germany and the United Kingdom (UK) and find the answer of how the EU overcome the CSDP question…

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.

Up to 50% of individuals with Parkinson's disease develop cognitive impairment over time; this study explores the use of 'practice effects' on neuropsychological tests as an early predictor of cognitive decline.

This thesis seeks to combine two different research topics; Multi-Objective Optimization and Complex Network Analysis.

Using E. coli bacteria to convert a toxic compound in the soil on Mars into oxygen to make life on the planet possible. A team of thirteen Leiden students are taking part in the annual iGEM competition with an entry based on this idea. iGEM is an international competition for students where they use…

Book historian Erik Kwakkel found an intriguing snippet of text earlier this week, that bears unexpected evidence of some of the problems encoutered by early printers: censorship and the affiliated fuss of seeking and printing Church approval.

The Leiden Observatory was very pleased to welcome eight bachelor’s students from Beijing Normal University at 8 July for the BNU Astronomy Summer School. In two weeks’ time, the Summer School students followed an interactive programme in computational astrophysics. ‘It’s surprising how much you can…

How does self-reliance lead to a decrease in collaboration for public goods?

Examining policy integration's adjustment to diverse implementations in cross-border crisis management, the article analyses institutional choices' impact on the process.

Combining geometry and number theory. That is what Dr Jan Vonk of the Institute of Mathematics receives a Vidi grant for today. ‘By fusing these two disciplines we may be able to solve a century-old mathematical problem.’

How do the residents of the Kooi neighbourhood in Leiden find living there? What can we do about loneliness? In this extraordinary academic year, students have been conducting all sorts of research, in Leiden. They presented their initial findings and recommendations at a Learning with the City meeting…

The information below concerns courses that our group teaches in Leiden. 

All the data stored and processed by our computers is encoded as sequences of zeros and ones, called bits. Quantum computers offer an alternative to this traditional way of encoding and manipulating information.

Below you can find lists of Leiden-based and international organizations working on Central Asia, and an overview of useful resources on Central Asia.

Following the terrorist attacks in Paris (November 2015) and Brussels (March 2016), Belgium’s counterterrorism policy has been heavily criticized – domestically and worldwide.

Leiden University's interdisciplinary research programme SAILS funds young interdisciplinary scientists working at the intersection of AI and other fields. How do these researchers experience the work?

Foster children’s behaviour is more problematic than that of their peers in ‘normal’ family situations. However, it is difficult to determine the exact cause of behavioural problems. Anouk Goemans, a researcher in clinical child and adolescent studies, calls for more screening and monitoring. PhD defence…

We show that Kirchhoff ’s law of conservation holds for non-commutative graph flows if and only if the graph is planar. We generalize the theory of (Euclidean) lattices to infinite dimension and consider the ring of algebraic integers as such a lattice.

Healthcare robots and AI is a project that investigates the legal and regulatory aspects of healthcare robot and Artificial Intelligence (AI) technologies

The aim of the RAISE study is to investigate how resilient people respond to stress. Specifically, we will study how key biological systems (HPA-axis, immune system) interact with the brain and social environment in order to facilitate resilient functioning after childhood adversities.

Understanding what motivates foreign fighters to go and fight in war zones and analysing their social environment offers a basis for preventing them from going.

Leiden University aims to equip its students for the world of tomorrow. All our teaching programmes promote international knowledge, global awareness and intercultural skills.

Our current lifestyle is not sustainable, and we know it. Our carbon-based economy causes climate change, and our livestock threatens the rainforests. We also know what we ought to do to save the planet: decarbonize the economy and change our diet. However, too many people lack the moral motivation…

European policy affects our lives: from air quality to the frequency of a bus service. Leiden researchers analyse how the European Union functions, how countries apply European policy and whether this policy actually provides solutions and delivers.

The research specialisation offers you the opportunity to spend two full years on training in applied mathematics to become an independent scientist with a strong theoretical basis.
