From the universe to the smallest particles, Leiden University conducts groundbreaking research into the discovery of new worlds, revolutionary technologies that make such research possible, and the legal, social and ethical aspects that accompany these developments.

In understanding the quantum world - the tiniest particles that make up our world - Leiden is at the forefront of research and education. For example, we conduct research into the qubit, a building block of the quantum computer. These computers can perform calculations at incomprehensibly faster speeds than ‘classical’ computers and could therefore lead to breakthroughs in many scientific fields, including the discovery of new medicines and materials. In addition, we are one of the world’s leading institutes for research and education on the origins of the universe, the expansion of the cosmos and the formation of planets beyond our solar system. Leiden also contributes to the development of the world’s most advanced observational instruments, such as the Extremely Large Telescope (ELT) and the James Webb Space Telescope.

Leiden scientists excel in socially relevant interdisciplinary research, both within Leiden University and in collaboration with public and private institutions in the Netherlands and abroad. For example, we investigate how quantum science and technology can be communicated to different audiences and what effects this has; we advise governments, international organisations and businesses on space law; and we provide innovative education at the intersection of these fields for bachelor’s, master’s and PhD students.
