Researchers propose a new system for quantum simulation

Researchers from the universities in Mainz, Frankfurt, Hamburg and Ulm have proposed a new platform for quantum simulation. In a theoretical paper recently published in...

When will artificial molecular machines start working for us?

Physicist Richard Feynman in his famous 1959 talk, "Plenty of Room at the Bottom," described the precise control at the atomic level promised by...

Scaling up: The future of nanoscience

In the late 1950s, Richard Feynman famously imagined a science where researchers and engineers could achieve remarkable feats by manipulating matter and creating structures all the way down to the level of individual atoms. Now, over fifty years a...

Silicon storage: That’s a lot of data!

Richard Feynman once said that all the information in all the books in the world could theoretically fit in a cube 1/200th of an inch on a side. Looks like he got it right, says Technology Research News. Reporting on advances in data storage, the magazine says researchers at the University of Wisconsin, Madison have demonstrated the successful use of single silicon atoms to represent the ones and zeroes that are modern data storage. The result, in theory, is the ability to store the equivalent of 7,800 DVDs in one square inch of material. Engineering limitations mean writing atomic bits is impractically slow at the moment. But the Madison work is a realistic analysis of bit stability and recording density, says one scientist who has examined the work.
