Breakthrough toward a new breed of computing

Physicists at the University of Arizona have achieved a breakthrough toward the development of a new breed of computing devices that can process data using less power...

"Spintronics has the potential to overcome several shortcomings of conventional, charge-based computing"...

Current microprocessors digitize information into bits, or "zeroes" and "ones," determined by the absence or presence of electric charges.... In spintronics, only the orientation of an electron's magnetic spin determines whether it counts as a zero or a one...

Story here

Amazing stuff happening!

Spintronics could be a stepping stone for quantum computing, in which an electron not only encodes zero or one, but many intermediate states simultaneously

Say what?? wow! Seriously.

This is full of holes IMO

More holes than the quantum-mechanics equivalent of a swiss cheese.

I can't imagine how they will keep a bunch of electrons in place while they test the modal spin of the bunch. Much less when the memory circuit is unpowered, which is one of the main purposes of the "project".

"Harnessing quantum mechanics is like being a blindfolded person in a dark room trying to find a black cat which isn't there".

Re: Breakthrough toward a new breed of computing

It's right behind cold fusion. I wouldn't sell your Intel stock

Nah, I'd never buy tech stock.

Anyway I only wish I had nVidia stock back in 1998!
