Researchers claim quantum breakthrough › News in Science (ABC Science) News in Science Thursday, 26 April 2012 Connor Duffy and staffABC Giant leap Researchers say they have designed a tiny crystal that acts like a quantum computer so powerful it would take a computer the size of the known universe to match it.
Details of the crystal, which is made up of just 300 atoms, are published today in the journal Nature. "Quantum computing is a kind of information science that is based on the notion that if one performs computations in a fundamentally different way than the way your classical desktop computer works," says study co-author University of Sydney's Dr Michael Biercuk.

Einsteins archive now available online - StumbleUpon. (PhysOrg.com) -- If you ever wanted to glimpse into Albert Einstein's thoughts, now you can.
Last week, the complete catalog of about 80,000 documents written by or addressed to Einstein—letters, postcards, notebooks, and other papers—was made available online by the Hebrew University of Jerusalem and the Einstein Papers Project (EPP) at Caltech. The archive is the result of more than two decades of collecting and researching. Einstein left a collection of 40,000 personal papers when he died in 1955; since 1986, 40,000 more documents have been collected—most of them by the EPP staff—says Diana Kormos-Buchwald, professor of history at Caltech and director of the EPP. One of the archive's highlights is a handwritten manuscript for a 1946 article entitled "E=mc²: On the Most Urgent Problem of Our Time," which was published in the magazine Science Illustrated.
Another notebook, from 1918–1919, contains Einstein's lecture notes on special relativity.
