Today's quantum computers are no more than experiments. Researchers can string together a handful of quantum bits -- seemingly magical bits that store a "1″ and "0″ at the same time -- and these ephemeral creations can run relatively simple algorithms. But new research from IBM indicates that far more complex quantum computers aren't that far away.
In the ongoing quest to push processor performance, the key is being able to effectively shrink their component parts. A new transistor, based on a single atom, may go further than helping speed things up: it could shatter Moore's Law.
