Superfast light source made from artificial atom

New research results from the Niels Bohr Institute show that light sources can be made much faster by using a principle that was predicted theoretically in 1954. Superfast light sources can be used, for example, in lase…

Massive investment: From theoretical quantum physics to usable quantum technology

In a major new effort to translate quantum physics into practical quantum technology, the Innovation Fund Denmark has therefore invested 80 million kroner in a nationwide project involving three universities.

Protected Majorana states for quantum information

Quantum technology has the potential to revolutionize computation, cryptography, and simulation of quantum systems. However: quantum states are fragile, and so must be controlled without being measured.
