‘Quantum technology is going to change the world, but most people don’t feel connected to it. I want to change that,’ says Julia Cramer, assistant professor at Leiden University. Known for her passion for science communication, Cramer actively seeks opportunities to share the wonders of quantum technology…

Besides physics, the sleep of PhD students also benefits from Vitaly Fedoseev's PhD research. He will receive his doctorate on July 7 for his work on optomechanics within quantum mechanics. And also on a setup that eliminated the need for PhD students to push a button every hour for 72 hours.

A suitcase as a messenger of quantum science. That is the idea behind QuanTour, a project connecting researchers from 12 European universities. In December, the suitcase landed in Leiden. A month later, it is time to pass the baton to Copenhagen. But what happened to it in Leiden?

On the 8th of March the first "introduction to entrepreneurship" boot camp was held at PLNT specifically for PhD researchers at the LACDR. During the two hour block topics such as "the core of entrepreneurship", "spotting opportunities" and "what is your value proposition" were discussed.

Recently, we have been welcomed our new CSC PhD candidates. Together with the faculty of Science and Leiden Institute of Chemistry (LIC) we have introduced different aspects of living in The Netherlands, and we have done activities to get to know Leiden city, the University and our institutes. As part…

Quantum Rules lab van Leiden Universiteit biedt proefjes en experimenten voor middelbare scholieren om te leren over kwantum natuurkunde. Henk Buisman vertelt over het 5 jarige jubileum.

Jianfeng Ge and Milan Allen of Leiden University look for majorana quasiparticles using shot noise measurements

On December 10, Kazakh pianist and composer Rakhat-Bi Abdyssagin will perform at the Stadsgehoorzaal in Leiden. A remarkable event where music and modern physics come together.

The faculty introduction morning was held on Tuesday 31 August as part of the University’s OWL activities. Our new international exchange, master’s and advanced master’s students from more than 50 countries were welcomed to the faculty.

‘Jelena Prokic, university lecturer and researcher at the Leiden University Centre for Digital Humanities, will be preparing students for the challenges and opportunities of the digital world. In September, six modules will start on subjects such as statistics and digitally searching through texts.…

Tjerk Oosterkamp of the Leiden Institute of Physics managed to do the first-ever measurement of gravity on a tiny particle - just 0.43 milligrams - where the quantum regime starts. He explains in Physics World why this is so challenging.

Using 2D materials, physics student Romme van der Kemp developed a nanochip that is extremely small ánd scalable. This is needed to make all kinds of technologies better, faster and smaller. He has been nominated for the FWN Young Talent Award 2023 for his research.

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,…

More and more countries have decided to introduce compulsory vaccination. According to various experts, compulsory vaccination, under certain conditions, could help the situation in the Netherlands.

Petr Steindl works on quantum dots in microcavities for his PhD research. He manipulates single-photons to create complex structures of light. Applications could include quantum communication and gates for quantum computers.

Lecture, Tuesday Talks: Science Insights

Tjerk Oosterkamp's group is conducting what is perhaps the coldest research in the world. The researchers have cooled a sensor to below 2 millikelvin - almost as cold as absolute zero. This allows them to make extremely sensitive measurements. PhD candidate Jaimy Plugge helped build the setup: ‘We are…

Lecture, NGL-lezing

A tour, presentations, drinks, and a quiz: new employees were warmly welcomed at the first faculty onboarding session. On a Thursday afternoon, they got to know the faculty.

Researchers Rowie Stolk and Caelesta Braun’s ‘Litigation in the name of public interest’ Kiem project included an interdisciplinary workshop on the same topic. For starting PhD candidates in particular, this was the chance to build valuable connections.

Is it possible to measure subtle oscillations caused by dark matter moving through the earth? A Dutch-American physicist team have discovered a new route toward what could be the first-ever measurement of ultralight dark matter. They suspended a microscopic magnet inside a superconducting enclosure,…

In the Netherlands, people probably grew up with De Fabeltjeskrant (a children’s show, ed.), but in France an introduction to fables plays a much more important role in a child's upbringing. PhD candidate Céline Zaepffel studied the role of fables in French education and teaching methods. It turns out…

Last year, the Faculty of Humanities started organising onboarding afternoons, where new staff members can get to know each other. ‘All new staff members are welcome.’

For many years, he was active in various management positions at the LION and even after his retirement he is still very involved. Professor Jan Aarts leads the Leiden hub of the Quantum Delta NL growth fund and is now temporarily responsible for national educational activities. In this way, he is helping…

Based on the results of a language-switching experiment, PhD candidate Fatemeh (Simeen) Tabassi Mofrad MA and Professor Niels Schiller have discovered that the traditional categorisation of brain areas is not sufficient. They published their research findings in the scientific journal NeuroImage.

Proton therapy is a new way of treating cancer in which radiation doses are delivered more precisely. This results in less damage to surrounding tissue and fewer side effects.
