Can we make quantum devices from quantum surprises? And can we explore and build life from the nanoscale up?

Promotor: Prof.dr. C.W.J. Beenakker

With the help of quantum mechanics, digital quantum hardware may be able to tackle some of the problems that are too difficult for ordinary computers. But despite these expectations and the ongoing effort of the research community, reliable quantum computers are not yet realized in a lab setting.

This thesis describes how to scale down concepts of macroscopic mechanical metamaterials to the thermal scale using a system of flexibly-linked colloids.

How can computers help design optimal buildings? PhD student Koen van der Blom makes algorithms that take into account all kinds of different architectural requirements, in order to reach the best compromise. And that is quite difficult: 'Algorithms do not automatically understand that a building that…

We will use Artificial Intelligence to make an intelligent, multilingual search engine for archaeological texts, which will enable new discoveries about the human past.

The Centre for Indigenous America Studies (CIAS) at Leiden University is designed to coordinate and promote the teaching and research of Indigenous languages, literatures, cultures and cultural heritage.

Patients on patient forums share all sorts of things about their illness: from side effects and advice to messages of support. PhD candidate Anne Dirkson uses artificial intelligence (AI) to retrieve this information. ‘Ninety per cent of the side effects weren’t officially registered.’

With 8.9 million euros from the Danish National Research Foundation, Aarhus University and Leiden Observatory will establish the Center for Interstellar Catalysis. The centre is led by Aarhus professor Liv Hornekær and aims to find out how and when the building blocks of life formed in the Universe.…

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,…

A signal that is present both in the centre of our Milky Way and in distant places in the universe could reveal the origin of dark matter. This is what Leiden physicist Alexey Boyarsky concludes in an article in Physical Review Letters.

If you replace the standard hydrogen atoms in ice with a heavier variant, something odd happens. The volume occupied by the molecules increases by 0.1 per cent. Leiden chemist Jörg Meyer and his colleagues have created a theoretical model that describes this behaviour. Their research appeared on the…

The Leiden University Green Office has some great news: you can now make the most environmentally-friendly search engine - Ecosia - your default on a public LU computer!

In this dissertation (titled: Exploring the Synergies between Transfer in Reinforcement Learning and Procedural Content Generation) we explore how the two research fields named in the title, namely Transfer in Reinforcement Learning (TRL) and Procedural Content Generation (PCG) can synergize togethe…

Zeger van der Wal, Professor by special appointment Ien Dales Chair at Leiden University, and Mehmet Akif Demircioglu, Assistant Professor ar the Lee Kuan Yen School of Public Policy, researched the effects of ethical culture and ethical leadership on realized innovation.

The Faculty of Social and Behavioural Sciences brings together high-quality research and outstanding teaching in the disciplines of cultural anthropology, education and child studies, political science, psychology, science and technology studies, as well as in multidisciplinary approaches.

Before embarking on your studies at Leiden University, it is important to thoroughly research the financial aspects of your stay. Look into the cost of living and studying in the Netherlands, and find out about all the available sources of financial aid. There are many options available.

What are the key technical, social, regulatory, economic, and ethical considerations for scaling up ocean-based Carbon Dioxide Removal (CDR) approaches, and what integrated assessment frameworks and governance structures are needed to facilitate their implementation at scale?

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

Researchers using remote sensing technologies have characterized pre-Columbian regularly-shaped earthworks in forests in Central America and the Amazon. In tropical forested mountains in South America, two challenges arise when identifying archaeological sites through remote sensing. Firstly, sites…

The Global Abolitionisms Network, established in 2015, is an international network of scholars working on antislavery activism and abolitionism. It is affiliated to the Leiden Slavery Studies Association.

The archaeology domain produces large amounts of texts, too much to effectively read or manually search through for research. To alleviate this problem, we created a search system (called AGNES), which combines full text search with entity and geographical search.

Increasingly, primary sources from the period before the emergence of digital media are being digitized. These “digital surrogates” have facilitated the work of (historical) researchers; instead of having to visit several archives, libraries and other places, the (primary) sources appear in front of…
