Quantum Computing Gets a Step Closer With Seven-Atom Transistor

Quantum computing just got a little bit closer, after an Australian team of researchers unveiled a seven-atom transistor. Measuring just four billionths of a meter and embedded in a single silicon crystal, it acts as a switch on a chip and paves the way for faster processing in an even smaller package. The team, from the Centre of Quantum Technology at the University of New South Wales, did the tricky stuff by hand, which means that commercial versions of their breakthrough will be at least...
