The race to build the first quantum computer is still ongoing, but Morten Bakker has made big step forward in that process with qubits. A qubit is a unit of quantum information that can be produced in large numbers on chips. Qubits capable of exchanging photons (light particles) could be used in the…

Leiden Law School offers different intensive Master's programmes, that provide tremendous opportunities for talented students.

A suitcase covered with stickers from various universities, containing a quantum light source. Since April 2024, this suitcase has been visiting scientists in Europe researching single photons: the smallest possible quantity of light. The suitcase, also called ‘Q-torch’, travels from lab to lab like…

What does the future of quantum look like? Vedran Dunjko (Assistant professor at LIACS and LION) is co-founder of the applied quantum algorithms (aQa) leiden interdepartmental initiative research that will investigate this. They are part of the Quantum Delta NL consortium that was recently awarded substantial…

Much of the work of Serge Fehr, Professor of Quantum Information Theory, is abstract and theoretical and comprehensible to very few people. But his work helps make the digital world safer so that in future our internet banking will still be problem free, for instance. He will explain more in his inaugural…

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…

The programme guarantees a thorough experience on the frontline of physics research with a practical training of communicative and computer skills.

Former PhD, Bachelor and Master students of the Van Exter Lab

This is the physics summer school of Leiden University. It is part of the Leiden Institute of Physics (LION). The summer school is intended for Bachelor (BSc) students in physics. It covers topics from quantum matter and optics, to biological & soft matter physics and cosmology and theoretical physics.…

At the center of this research project lies a practice-based, artistic exploration of the impact of digitalization on the lived reality of both physical and cognitive labor.

This year's Nobel Prize in Physics goes to quantum physics research. The prize will be awarded on December 10 in Stockholm. Physicist Bas Hensen explains why this is important and how his research in Leiden relates to it.

Watching and analysing hundreds of TEDx talks, that too can be research. That becomes clear from the work of PhD student Aletta Meinsma, who is studying potential problems in popular communication about quantum technologies. She explains how she approaches this and why it is so important.

The main topic of this PhD thesis is the Arakelov ray class group of a number field, an algebraic object that contains both the ideal class group structure and the unit group structure.

The specialisation consists of 120 European Credit Transfer System (EC) points and includes mandatory courses and electives (60 EC) and two research projects (60 EC).

Optical detection of a single electron using a single molecule has never been done. Leiden physicist Michel Orrit and his team have now identified a molecule that is sensitive enough to detect an electron at a distance of hundreds of nanometers. The results are published as a cover article in ChemPh…

The most famous cat in science is Schrödinger's cat, the quantum mechanical mammal, which can exist in a superposition, a state that is alive as well as dead. The moment you look at it, one of both options is chosen. Leiden University physicists simulated an experiment to catch this mysterious moment…
