Effective reflection of light for quantum technology

Researchers at the Niels Bohr Institute have developed a new method where they create a very strong interaction between light and atoms, which means that the light can be controlled and reflected on a glass fiber.

Eugene Polzik on the steering committee for EU quantum technology flagship

The EU will launch a €1 billion innovative quantum technology project. In order to develop a program of research, a steering committee of senior researchers and business people has been established. From Denmark,…

Optical magnetic field sensor can detect signals from the nervous system

The human body is controlled by electrical impulses in, for example, the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which can be used to diagnose various diseases.

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.
