I wonder if this is one of the "within 20 years" sort of think we've heard about generating electricity through fusion for the last 40 years, or if it's one of those things which has been predicted regarding computers which has happened faster than seemed possible. The article implies it's a distinct possibility this kind of computing will exist shortly.

"Putting electronics in a spin."

"With quantum computing you are able to attack some problems on the time scales of seconds, which might take an almost infinite amount of time with classical computers," said Professor David Awschalom of the University of California, Santa Barbara.

"Spintronics, also known as magnetoelectronics, is an emerging technology that harnesses the spin of particles."
