The exotic material in D-Wave’s quantum chip is niobium; cool it enough and it becomes a superconductor. When ordinary metal conducts electricity, the electrons carrying the electric current collide with the imperfections in the metal and you get resistance. When you cool superconducting metal like niobium, the metal’s electrons form Cooper pairs where the motion of one electron is matched by an equal and opposite motion of the paired electron, which stops the electrons hitting the imperfections and generating resistance, which means the electrons flow freely without you needing to pump in extra current. When the Cooper pairs enter the Josephson junctions in the chip – made up of two segments of superconducting niobium linked by a weak insulating barrier – they break up, creating electron-like quasi-particles that can tunnel through the insulator in the junction, effectively conducting the current through the junction.
The niobium is arranged in rings through which the current can flow clockwise, anti-clockwise or in a mixture of both directions – corresponding, according to Rose, to the 0, 1 or superposition of the two values in the quantum bit of information (qubit) that quantum computing is based on. “The chip is a series of metal traces on a silicon substrate; the substrate is the same as you’d use for any semiconductor process but on top are layers of metal interrupted by insulators. This is an entirely metal based magnetic thing where all the information is stored in the direction of the current flows around the metal loop and interruptions.”
The direction of the current converts into a value for the qubit based on whether that qubit has a bias towards one direction (0 or 1), whether neighbouring qubits are running the in same or opposite directions and the energy barrier between the different qubit states. The current chip, Leda, has 28 rings, giving 28 qubits, but they’re not all interconnected to each other, only to a number of ‘neighbours’. The Cooper pair in the niobium are technically bosons so they all exist in the same quantum state, Rose claims, which gives the entire superconductor quantum properties even without interconnecting every qubit. Reducing the number of interconnections simplifies manufacturing and has enabled D-wave to go from 2 qubits in 2002 to 16 in 2007, 28 today – and 512 and 1024 over the next year, if things go well.

LIKE A GLOVE!
I WANT TO SEE THAT THING PWN SOME GAMES >< I KNOW A LITTEL OVER BOARD BUT I CANT DREAM CANT I?
dam you beat me to 1st post ?> o wait that was me i just was to fast about posting i did not sigh in o well i cant prove it now but i know it was me >< LIKE A GLOVE
oops i said a bad word dont report me >< any ways the 1st post was me i was to quick to sigh in and yes i have made 3 post so sue me. LIKE A GLOVE
I still wish someone would explain exactly how quantum mechanics and quantum computers work. Do they actually defy the laws of physics or what? I didn't think that was possible.....
I meant to say "in layman's terms"
Very cool, i'd also like to see that pwn some games. However judging by what they say, it'll be very difficult to do if it's even possible.
BTW what does it matter who got first post anyway? lol
This is some wild funky alien technology sh#t... Yeeeehaaa!
Quantum computers process information with the "electron pairing" effect they naturally operate with, meaning it operates in such a way when one of the 28 bits is "doing something", it affects other parts of the chip in such a way they "do the same thing" naturally...it has very deep implications because it would basically SCALE LIKE CRAZY....NATURALLY....we are still in its infancy w/ 28 QBits, i dont even immagine what is will be like with 512...1024....a Giga QBit.....a Tera Q Bit.... they would all scale naturally... whatever we an do now whit it will be done faster and better when wider versions of the chip come out, withought the need to re-coding i immagine (Totally different from the way we program now with the current multi-core chips needing special programming to take advantage of more resources).- my 2 centz.

basically, a quantum computer does not have to do "work" to get an answer. The "work" it does involves electrons and atoms. The problem is, is that when the "computer" reads the atoms/electrons, they are destroyed. So, the data can only be read once. But as mentioned in the article, code cracking would be very easy, as the computer would only have to work with one atom. Basically, the future quantum computer will be able to crack any code, instantly.

Quantum Physics are laws that are far more complex than regular everyday Physics. They do not defy but rather redefine and enhance our understanding of physics at a much smaller scale (Smaller than atom size)
Games aren't really an area that would benefit directly from Quantum computing. The benefit is for other fields, like mathematics, communication, cracking encryption, physics. Quantum does not mean faster, it means they operate in a fundamentally different way and have different applications. Just like the stack of IBM QS22 Cell Blades next to me (Which don't even have video cards), they are for a totally different purpose and in some cases even if they could run a normal game might even be slower. High-Performance-Computing is a very different field, and it has to be specifically programmed for, which is why the article mentions they are advancing the new SDKs to allow things to run.
My computers don't even have a real "OS", they have micro kernels which only have one program installed, and that program is specifically crafted to fit inside the 256KB of L2 Cache on the IBM Cell Processor to prevent the system having to page regular, slow, system RAM.
The stuff is written in C, and then hand-tuned in assembler.
That does not mean the development is not exciting, its just that like most major science changes, the action is far from the end user and it will take products a while to trickle down to something we use everyday. Ironically, by the time it gets to us, most people will have no idea which technologies brought them to fruition in the first place.
I wonder how fast an E8500 could run at -270ºC.

You might have a good idea when the OC competition ensues. I'm sure you'll have some guys throwing -200C nitrogen at 8500's.
One question: Does it overclock? That cooler should at least allow for a 30% overclock...
I want one!
this is all good and fine. Will it play Crysis
Intel will buy them in after they make all that profit from Nehalem and release quantum computers for commercial use as soon as they figure out how to make a "safe", commercially viable, 3 Kelvin refrigeration units. Coolermaster will then release a 2 Kelvin unit for overclockers 3 months later...
Unfortunately it will NOT be able to play Crysis at 60FPS.
Reaching temperature as mentioned above would lead to super conductivity . Which people are yet to incorporate in daily usage . This is no area for child's play (games)
Where quantum computers will one day actually see uses :
1. scientist mapping the exact distances of various stars from our solor system (curnetly this can on be guesstamated usuing doppleganger effects in light spetrum it's not very acruate , whiel we can get a "this starr is apoximately 3 light eyars from us" we cant get an exact milage for star distances) quantum computing would change how accurate science is in gauging distances in space
2. Space navigation : for both now and teh future quantum computing could increase space navigation safety by 100% , if any of you watched appollo 13 you would see several ponts where the peoepl ahd to hit percise navigation , whil current computers can naivigate OK , there is still LARGE margin for error when it coems to landign a spcace craft , and or going to another planet , again quantum comptuers would make this error margin non exsitant thus increasing teh saftey of space travel , in the future there is no telling how far this could be taken for navigational purposes.
3. any field where extremely large math numbers are crunched (note i sued space ing eneral on my otehr two definitions mostly because space mroe than any field deals with large nubmers adn multiple varrible sthat have to be considered) other fields that use this could things such scinetist that study earth quakes, or weather scientist that study weather patterns / hurricane wind pressure and the like.
however , I doubt that quantum computing will ever be needed just for browsing the web , in teh long term i think conventional computers will be as viable tomorrow as they are today , for teh average computer user and or gaming enthusiast
