ScienceDaily (Aug. 16, 2012) — Quantum computers promise to reach computation speeds far beyond that of today's computers. As they would use quantum effects, however, they would also be susceptible to external interferences. Information flow into and out of the system is a critical point.

Researchers from KIT with partners from Grenoble and Strasbourg have now read out the quantum state of an atom directly by using electrodes. In the journal Nature, they report on the stable interface between classical and quantum world.

"Normally, every contact with the outer world changes information in a quantum mechanical system in a completely uncontrolled manner," explains Professor Mario Ruben from Karlsruhe Institute of Technology. "We therefore have to keep the quantum state stable and shielded. On the other hand, information has to be read out in a controlled manner for further use."
