Lecture

A high performance computer or supercomputer owes its massive processing capacity to the fact that it chops a single overarching task into a whole series of smaller tasks. It simultaneously tackles each of those smaller problems.

We are becoming ever more dependent on automation systems in our daily lives. Computer Science is more than programming; you integrate maths and logic into the development of systems and solutions that can be applied in all fields - from business to healthcare.

Physicists understand little about quantum matter, which is a building block of future quantum computers. Theorists have now discovered that black holes with ‘dreadlocks’ harbor a similarly exotic order pattern, which makes calculations on quantum matter easier. Publication in Physical Review Letter…

Quantum Delta NL, a research programme in which Leiden University participates, has been awarded 615 million euros from the National Growth Fund to help develop the Netherlands into a top player in quantum technology. This has been announced at the presentation of the honoured proposals in The Hague…

High Performance Computing (HPC) is becoming ever more important as a research tool in many research areas across all research domains. A University facility, providing serious computational capabilities, combined with easy and flexible local access, is a strong advantage for these research areas. It…

This dissertation investigates Extended Lexical Units (ELUs), elements that are bigger than just one word and which are stored in the Lexicon.

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

Physicist Kaveh Lahabi’s research on quantum materials led to the launch of a new company: QuantaMap. With his colleagues, he developed a sensor that will improve the production of quantum computer chips. ‘It turns out that what I need for my fundamental physics research is also very useful for the…

Large-scale computing infrastructure, such as supercomputers, cluster, and clouds, are already pervasive, most members of our society interact with them daily: social networks, government services, media streaming services--all systems heavily interfacing with the members of our society--are powered…

Telling sensationalised stories, exaggerating benefits and understating the risks: creating ‘hype’ about something doesn't sound like something a responsible scientist would indulge in. Or could we also use hype in a ‘good way'? What could we achieve by opening up quantum futures for wider discussions,…

Tic tac toe, but with quantum effects. That makes learning the principles of quantum technology a piece of cake. This is the aim of a new start-up founded by researcher Evert van Nieuwenburg: QuantumPlayed. ‘Quantum is all around us and everyone should be able to learn about it.’

Rare-earth materials are prime candidates for storing quantum information, because the undesirable interaction with their environment is extremely weak. Consequently however, this lack of interaction implies a very small response to light, making it hard to read and write data. Leiden physicists have…
