[MaximumPC] Purdue Researchers Inch One Step Closer To Quantum Computing

We've already covered a new ThinkGeek gadget today, so let's keep the "Think Geek" ball rolling and talk about a concept that keeps real-life geeks awake at night, jittering at the thought of its awesomeness: quantum computing. Even though Lockheed Martin signed up to buy an underperforming "Maybe it's a quantum computer" from D-Wave One a few months back, the face-melting power we think of when uttering the words "Quantum computer" is still a long ways off. A pair of researchers at Purdue University just inched it a little bit closer to reality, however.
Shhhhh!

After cooling the gallium arsenide to absolute zero – about -460 Fahrenheit – and applying a magnetic field to the material, the electrons inside break the laws of single-particle physics and enter a correlated state, in which changes to one electron reflect in the other electrons. The whole theory of quantum computing is based upon particles in correlated motion.
So that's a bit of a hurdle...
I'll wait until the C30 stepping comes out and stick with my 512 core silicon CPU FTTB to make sure it's not going to create some type of a minuscule black hole or open a portal and eat my computer (which are real and actual concerns).

Wow,this is truly impressive!

I truly hope I can get to see quantum computers when I'm 40 or 50, maybe before that.

Yeah but the point is that the conditions to achieve anything like quantum computing aren´t anything like our dayly environmental conditions. What I mean is room temperature range with a decent tolerance band.. I think that´ll be long ways off still...

Umm and how did they achieve this? I thought it was impossible, with today's tech, to reach absolute zero. The closest I've ever heard of scientists getting was a few Kelvin away.

I guess it was just as close to absolute zero as they could?

I was thinking the same thing. As far as I know it's impossible to reach absolute zero because there will ALWAYS be some heat no matter. Kind of like pure gold will never be 100% pure since there will always be traces of other metals no matter how small.
