Livestream Science: The Quantum Computer

Quantum Computer - livestream lecture: Tuesday 20 October 2026, 19:00–21:00, Maribo Bibliotek, Maribo. Admission is free.

This evening features a lecture from Aarhus University broadcast on the big screen, where physicist Klaus Mølmer introduces the world of quantum physics. He discusses the new "quantum revolution", where technologies are being developed based on quantum physics' most paradoxical phenomena, and explains how quantum computers work and what they can be used for.

Quantum physics describes the microscopic world of atoms and molecules, which differs markedly from our everyday experience - atomic particles can apparently be in multiple places at once, and measurements of them always yield random results. When quantum physics emerged in the early 20th century, it shook many physicists' worldview, but its predictions have since been confirmed with great precision in both physics and chemistry.

Klaus Mølmer, professor of quantum physics, reviews both existing technologies and prospects for future technologies that exploit the quantum properties of atomic particles. Since the 1990s, Denmark and internationally have invested large sums in the race to develop quantum computers that can calculate many numbers simultaneously using atomic quantum states. The lecture provides insight into how far development has progressed and what quantum computers will be able to do when they eventually become fully functional.

The lecture is part of the series "Public Science Lectures from Aarhus University", where researchers present the latest discoveries in science. The level is high, but the lectures can offer something to everyone regardless of background, and admission is free. They are livestreamed from the Søauditorierne in Universitetsparken, Aarhus University, to cinemas, libraries, folk universities, cultural centres, associations, community halls, secondary schools, schools and restaurants throughout Denmark and abroad.

The evening is arranged in collaboration with Rotary Denmark. Participation is free, but registration is required. The lecture lasts approximately two hours.
