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.

Quantencomputer versprechen Rechengeschwindigkeiten, die weit jenseits der Geschwindigkeit heutiger Computer liegen. Da sie Quanteneffekte nutzen w�rden, sind sie aber auch anf�llig f�r St�rungen von au�en und der Informationsfluss in und aus dem System ist ein kritischer Punkt. Nun haben Forscher vom KIT mit Partnern aus Grenoble und Stra�burg den Quantenzustand eines Atoms mittels Elektroden direkt ausgelesen.

Read moreA long-time staple of science fiction is the tractor beam, a technology in which light is used to move massive objects - recall the tractor beam in the movie Star Wars that captured the Millennium Falcon and pulled it into the Death Star. While tractor beams of this sort remain science fiction, beams of light today are being used to mechanically manipulate atoms or tiny glass beads, with rapid progress being made to control increasingly larger objects. Those who see major roles for optomechanical systems in a host of future technologies will take heart in the latest results from a first-of-its-kind experiment.
