Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

An important discovery makes it possible to communicate complex information among multiple people without the message being cracked. The communication can also relate to complex information.

In this thesis the combinatorial use of bioorthogonal labelling and Electron Microscopy (EM)-based imaging techniques is explored to enable observations of specific molecular targets in their ultrastructural context within the cell.

Physicist Martin van Exter works with light at nanoscale, at the forefront of nanocomputer research. But as Director of Education he also has a vision for physics teaching. Inaugural lecture 18 November.

The small quantum world and our world of perception obey different laws of nature. Leiden physicists search for the border between both worlds. In an article published soon in Physical Review Letters they set an upper limit.

The close interaction between organic chemi stry and biology goes back to the late 18th century, when the modern natural sciences began to take shape. After synthetic organic chemistry arose as a discipline, organic chemists almost immediately began to pursue the synthesis of naturally occurring compounds,…

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…

Proving a quantum computer to be quicker than a normal one is one step closer. After a breakthrough in speeding up classical algorithms, researchers Vedran Dunjko and Casper Gyurik showed that only one quantum algorithm could beat its classical counterpart. They discuss their discovery in Quanta Mag…

Can cyclic peptides provide a new generation of antibiotics?

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…

This research focuses on the (Quantum) Dynamics (QD) of the reactive scattering of H2 from metal surfaces.

Laboratory, observation and modeling work on the dissociation of polycyclic aromatic hydrocarbons in interstellar environments and the formation of new molecular species through the fragmentation process.

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…

Even a small quantum computer should be able to simulate exactly the properties and behaviour of new molecules. This would take chemistry to an entirely new level. Better solar panels, more powerful batteries, saving lots of energy in the chemical industry: the applications have the potential to transform…

Leiden physicists Tjerk Oosterkamp and Dirk Bouwmeester have received a 1.3 million euro Science-Groot grant from NWO to catch a mystery at the core of quantum mechanics, together with Amsterdam physicist Jasper van Wezel.

To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

Advanced mass spectrometry of glycosphingolipids takes the central stage in this thesis. Investigations focus on characterization of glycosphingolipid metabolism in health and disease with emphasis to the detection and accurate quantitation of known and so far unknown glycosphingolipids and closely…

With his ice-cold nano force sensor, Tjerk Oosterkamp searches for the boundary between the quantum world and the everyday world. The Leiden physicist has received an NWO subsidy of 600,000 euros.

Leiden physicist Julia Cramer receives 50 thousand euros in funding for 'Let's talk about quantum', a research project on communication about quantum computing. A project for high school students by education expert Henk Buisman is also included in the NEWA ELSA funding.

Only 35 years old and already a research group leader, on his way to tenure. And: numerous papers, grants and fellowships to his name. Leiden physicist Jordi Tura i Brugués receives today the Young Scientist Prize for his outstanding contributions to quantum research.

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…

Assistant Professor Vedran Dunjko and his team received a gift from Google to support their quantum research. The research focuses on whether quantum computers can provide new ways of understanding the mysteries of high-energy physics.

As of 1 June, Serge Fehr has been appointed as Professor Quantum information theory at the Leiden Mathematical Institute (MI). Fehr is employed by Centrum Wiskunde & Informatica (CWI) and as of his appointment works one day a week at the MI. Fehr’s research is focused on quantum cryptology and will…

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

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…

‘We hope our paper highlights the possibilities and benefits of including artificial intelligence in quantum physics to do new discoveries.’ Vedran Dunjko of the Leiden Institute of Advanced Computer Science contributed to a paper that was published in PNAS last year and now received a Cozzarelli Prize…

Three researchers from Leiden University have received awards in the Quantum Technology programme within the National Growth Fund, organised by NWO in collaboration with Quantum Delta NL. Read more about these three futuristic projects.

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.
