Hewlett-Packard goes Quantum

Ok, so I'm a nerd, but I have good resources and have nothing else better to do... yeah right. Anyway, I have a google alert set to inform me of the latest news in “quantum physics computer research”. All the news today in this category related to Hewlett-Packard and how they begin to focus all their research on a replacement for silicon based transistors. In about 10 years transistors will go as far as they can go. Quantum physics to the rescue...

 "We are reinventing the computer at the molecular scale," said Stan Williams, one of the authors of the paper. "The crossbar latch provides a key element needed for building a computer using nanometer-sized devices that are relatively inexpensive and easy to build."

Transistors will be replaced with nano sized 'crossbar latches'. A crossbar latch is a small (nano sized) device that is able to maintain and restore signals (the '1's and '0's) as well as invert (or “compute“) them. These are the bare bones of computing; and now we are finding a new way of doing this with out transistors. These things are supposed to be available in the very near future (as early as 2012).

I think this will be making a LOT of noise in the next couple of years. Sign up for your google alerts now. :)
