Smart atomic cloud solves Heisenberg's observation problem

One of the most fundamental principles of physics, "Quantum Back Action", has been challenged by researchers from the Niels Bohr Institute, which has used laser light to link a vibrating membrane with cesium atoms.

Iron secrets behind superconductors unlocked

Due to magnetism iron should - theoretically - be a poor superconductor. Nevertheless certain ironbased materials possess fine superconducting properties. Why? Because the five unbound electrons found in iron...

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.
