Unavoidable disorder used to build nanolaser

Researchers at NBI have discovered that imperfect nanostructures can offer entirely new functionalities. They have shown that imperfect optical chips can be used to produce ‘nanolasers’, which is an ultimately compact…

Ultra sensitive detection of radio waves with lasers

When detecting radio waves ‘noise’ in the instrument limits how sensitive and precise the measurements can be. Now researchers at the Niels Bohr Institute have developed a new method where they can avoid noise by means…

10.8 million kroner for research into quantum information technology

Two researchers, Mark Rudner and Michael J. Kastoryano from the Niels Bohr Institute, have received support from the VILLUM FOUNDATION’s Young Investigator Programme for research into quantum information technology.

Eugene Polzik’s research chosen as the year’s best by Ingeniøren

Ingeniøren (The Engineer) has chosen Eugene Polzik’s research on teleporation as the year’s most important Danish research results in science. Eugene Polzik is the head of the research group Quantop at the Niels Bohr…

Decay used to construct quantum information

Usually, when researchers work with quantum information, they do everything they can to prevent the information from decaying. Now researchers at NBI have flipped things around and are exploiting the decay to create…

Quantum communication controlled by resonance in ‘artificial atoms’

Researchers at NBI among others have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state

Peter Krogstrup appointed assistant professor at QDev on nanowire growth

As of May 2013, Peter Krogstrup has been appointed assistant professor at the Center for Quantum Devices. He will be working on MBE growth of nanowires.

Quantum teleportation between atomic systems over long distances

The research group Quantum Optics at NBI has succeeded in teleporting information between two clouds of gas atoms and to carry out the teleportation – not just one or a few times, but successfully every single time
