Thinking about the quantum internet
Quantum computers deserve their own quantum internet. This is a network that dispatches information not in the form of bits - ones and zeros - but rather as qubits, just like in the quantum computer itself. In the view of Dirk Bouwmeester, a professor in Leiden’s Quantum Matter & Optics research group,…

It's just a phase: High-contrast imaging with patterned liquid-crystal phase plates to facilitate characterization of exoplanets
This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

Focal-plane wavefront sensors for direct exoplanet imaging: Theory, simulations and on-sky demonstrations
One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Quantum particles and bacteria without cell walls: KLEIN grant for Beenakker and Claessen
Are Weyl particles the ideal conductors? Do cells without a cell wall play a role in chronic Tuberculosis infections? Carlo Beenakker and Dennis Claessen want to answer these questions. They both received a KLEIN grant from the NWO. With these grants, NWO wants to stimulate innovative, fundamental r…

New research project makes the internet even better
How is it that the internet works so well, with billions of users sending millions of gigabytes all together every day? That's because the foundation of the internet is solidly set up. Yet sometimes there are problems on the internet. For example, when certain systems misbehave and disrupt the routing…

Protein condensates as Materials
We have recently discovered that there are biological proteins that phase separate out of solution much the way oil will de-mix from water (see movie). These form dense, liquid-like phases called protein condensates.

Packaging and accessing DNA molecules
Our DNA molecules are packaged by proteins in compact structures. The aim of this project is to understand how modern gene editing techniques nevertheless get access to their target in the DNA.

The quantum computer
The worldwide race to the quantum computer is in full swing. This computer can take on computing tasks that we can only dream of today, such as finding proteins that can be used as medicines in seconds flat. Leiden physicists have discovered how the Majorana particle can be used as a building block…

On the origin of patterning in movable Latin type : Renaissance standardisation, systematisation, and unitisation of textura and roman type
This PhD-research is conducted to test the hypothesis that Gutenberg and consorts developed a standardised and even unitised system for the production of textura type, and that this system was extrapolated for the production of roman type in Renaissance Italy.
