Mechanical metamaterials are man-made materials which derive their unusual properties from their structure rather than their composition.

We are interested in understanding the mechanics of soft materials, of which biological materials are prominent examples.

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…

We investigate the physics and design of mechanical metamaterial, intricately sculpted materials with properties set by their architecture.

American physicist and quantum computing pioneer Seth Lloyd is the 65th Lorentz professor. He will deliver the Ehrenfest lecture on 5 June, and several more lectures on quantum computing on 11, 18 and 25 June.

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…

In the weekly magazine “Mare” from Leiden University, an interview with the Leiden statistics prof. dr. Richard Gill has been published recently about his contribution to the Delfts quantum-experiment.

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.

Mass, time, space, and complexity — physicists in Leiden are launching eight new research projects tackling some of the most fundamental themes in quantum mechanics. Their goal: to push the limits of current quantum theories.

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

This work describes several studies into the electroreduction of carbon dioxide (CO2RR), both regarding mechanistical aspects and catalyst stability considerations. Mechanistic insights into carbon-carbon bond formation on a silver catalyst are described in Ch 2, were we find an acetaldehyde-like surface…

Mechanical metamaterials are carefully engineered materials whose properties are controlled by their structure, not by their composition, which allows using metamaterials to study and control physical effects in detail⁠.

Physicists at the Leiden Institute of Physics (LION) conduct fundamental research into physical phenomena. They are inspired by curiosity and the desire to know more about the world in which we live. This research has always paved the way for new practical applications. These are something that the…

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…

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.

‘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…

The 18.8 million euro NWO Zwaartekracht grant for quantum software which Amsterdam, Delft and Leiden landed collectively, means for Leiden University among others the appointment of two new permanent scientific staff members, who will each form their own research group, divided among Computer Science,…

Researchers found a way to run programmes that should be impossible to carry out on an imperfect quantum computer. Such programmes are very computationally demanding and the quantum computers that currently exist are not yet up to that task. Unless you use a clever trick, Simon Marshall and Vedran Dunjko…
