Scientists Teleport Information Between Ions a Meter Apart 220

erickhill writes with word that scientists from the University of Maryland have successfully transferred information from one charged atom to another without having it cross the intervening space of about one meter. The academic paper is available in the journal Science, though it requires a subscription to see more than the abstract. Scientists have previously teleported unmolested qubits between photons of light, and between photons and clouds of atoms. But researchers have long sought to teleport qubits between distant atoms. Light's high speed of travel makes photons good transporters of information, but for storing quantum information, atoms are a much better choice because they're easier to hold on to. 'This is a big deal,' comments Myungshik Kim, a quantum physicist at Queen's University Belfast in the United Kingdom. 'To store information as it is in quantum form, you have to have a teleportation scheme available between two stationary qubits. Then you can store them and manipulate them later on.'"

Politician Forces German Wikipedia Off the Net 569

Stephan Schulz writes "A German Member of parliament for a left-wing party, Lutz Heilmann, has obtained a preliminary injunction against the local chapter of the Wikimedia foundation, Wikimedia Deutschland e.V., forbidding the forwarding of the popular http://wikipedia.de to the proper http://de.wikipedia.org. Apparently Heilmann is not happy with the fact that his Wikipedia article (English version) contains information on his work for the former GDR Stasi, the much-hated internal secret service. Wikimedia Germany displays a page explaining the situation, and has announced that it will file an objection to get the injunction lifted. The German Wikipedia has more than 800,000 pages, and is hosted, like all Wikimedia projects, by the Florida-based Wikimedia Foundation, and hence beyond the effective reach of at least German politicians and judges."
