The five-atom computer

Researchers at IBM announced today that they had built a quantum computer consisting of five atoms. Take a look at this story for the details. If you aren't up on why quantum computing is such a big deal, the article provides a nice summary of the technology.

For those of you who want the short version, here's a nice quote from the article:

For certain types of calculations, like complex algorithms for cryptography or searches -- a quantum computer using several hundred more atoms in tandem would be able to perform billions of calculations at the same time.

Pretty heavy duty for a few hundred atoms.

Tip: You can use the A/Z keys to walk threads.
