UK researchers said they were
getting close earlier this year, but in one brilliant fraction of a second a gaggle of Yalies beat those limeys to the punch, with a team led by Robert Schoelkopf, a professor of Applied Physics at Yale, creating what's being hailed as the first quantum processor to actually
perform calculations. It's composed of aluminum atoms grouped together to form two quantum bits, communicating over an unimaginatively named named quantum bus that enables one to change the (wait for it) quantum state of the other. This first qubit shifter was able to maintain state for 1,000 times longer than any previous qubit ever produced -- but since its predecessors could only manage a nanosecond's worth of cognition we're still only talking a microsecond here. In other words: there's still a long way to go before you'll be slotting one of these into your gaming rig.

It's a start! I remember when we hit 1mhz everybody thought that was not possible same with Megabytes
Starting back from Slot processors that is!
did it disappear into an alternate reality?

@Quantumphysics
Dont we already?
this is one of the first articles that i've read on engadget in a long long time where i just thought "wtf" after finishing.
@simbadogg
Really, this is the first one? You must be new here....
A little hint: Engadget is like a really hot diseased whore. You know she's giving you the clap and probably 9 levels of AIDS, but damn she's hot. Why do you stay with her? All she talks about is frickin Apple news! You don't know, but you do stay....you do stay...and you find yourself saying WTF a lot to the things she says....maybe it's that her being so dumb is a turn on, knowing you're so much better than her.

Wow I was hoping that they would say something like, "Why is this picture related to the article?" I guess Engadget is going gay. Sad. Just kidding lol.
This is a really misleading story. People have done quantum computations before with more q-bits, and people have built q-bits with vastly greater coherence times than the one's in the article.
The real claim is that this is the first all solid-state quantum computation.
Proof? Links?
@Aaron Do your own research! Try googling: there are many established results and they should be easy to find. If you're interested in getting someone else to boil-down physics developments for you might I suggest you sign up to the excellent, and free, APS Physics bulletin http://physics.aps.org/ .
I didn't make the claim, the burden of proof is on Jony. If I was really interested in figuring that out I'd look for it, but I'm just questioning whether Jony here is talking BS or actually knows something.
It's a blog not a court: there is no "burden of proof"!
Anyway, I'll give you the benefit of the doubt and imagine that you really are interested in physics and not just some awkward internet type ...
The NMR people have been doing computation for a long time now on systems with more than two bits. There was a famous paper by Ike Chuang in 2001 that implemented a real search algorithm on an NMR quantum computer. http://dx.doi.org/10.1038%2F414883a . I'm pretty sure there were others before that with smaller computations but off the top of my head I can't point you to links. Nobody has figured out how to scale NMR beyond a few bits, for various pretty fundamental reasons.
Looking to other technologies that can get round this limitation, the leader is probably strings of trapped, laser cooled ions. There are two powerhouse groups: Rainer Blatt's group in Innsbruck , and the group of Dave Wineland at NIST (http://tf.nist.gov/ion/qucomp/papers.htm). They've both managed to entangle long strings of ions (8 I think is the record). There's a review here http://tf.nist.gov/general/pdf/2284.pdf .
Coherence times for trapped ions are vastly longer than those for solid state systems, including the one reported above. Amazingly, optical coherences of greater than one second have been observed in these systems by encoding the q-bit in a dechorence free subspace of a pair of ions (see below). Hyperfine coherences can be much longer than this.

Not that misleading. I have Incandescent light bulbs that have outlasted 80% of the XBOX 360's ever made.
Seems microsoft stays ahead... if they can manage to make the xbox last longer than couple of days this will get fixed in no time... :P
Zing!

Oh, come on. He's HOT (for his age)...
I certainly wouldn't kick him out of bed. ;)
I'd hit him...
I would too. Just not the way YOU meant it.
Well I'm pretty sure he meant hit him physically in a striking force, so I'm guessing you're suggesting otherwise.
Way to misrepresent the actual accomplishment, Engadget. Also, a quantum bit is called a qubit, not a qbit.
Doesn't matter as long as it conveys the point. http://www.bradrubin.com/Site/Blog/Entries/2009/1/16_Qubit_or_Qbit.html
Unless you're Q-Bert
WHAT THE ... ? MY EYES!
HAHAAH
Isnt that Hasselhof's pic with the quantum leap guys face photoshoped in there? LMAO
thats is one funny picture.
That Blake Johnson sure is a hot stud.
*$&#!!!
I was reading Engadget at a public cafe! Forget whether or not it makes me look gay - it makes me look gay for Scott Friggin Bakula!!!1! I could do better!
Awwwfuc. Ive been half body fro'd!
Am I the only one who recognises him as Cpt Archer?
ooooh captain!!
or Chuck's dad (aka Orion)
no , its not captain archer, its the guy from quantum leap. same actor, different chrachter.
*facepalm*
Oh boy.
Don't forget that Captain Archer saved planet Earth!!!!!!
Actually, I only recognize him as The Bakula Debacle
mmmm... T'Pol.
You so know Archer wanted to hit that.
Ah, the 70s and 80s... When chest hair was still cool.
I don't know about all of that... I still think your mom is cool.
A quick mutation has stopped all chest hair growage?
SO HOT!!!!!
Thank God nobody rushed in while I was reading it :p
It's amazing how close we are coming to all sorts of tech like this. Even more amazing is how in the year 2009, Microsoft still can't figure out how to build something that doesn't crash and burn (literally).
Anyone else wonder why Yale University invested in taking pictures of a shirtless Scott Bakula?
And by "actually does calculations" you mean they were testing out Crysis on it....... Its ok you can come clean.......
Yeah, and they were able to get 1,000,000 FPS!
Unfortunately, it was unplayable-
as they only ended up with 1 frame and then had to send it in to get refurbished.. (in their own box, no less!)
I have no quantum education, but I can't imagine they can make stable quantum computers that are cheap enough for consumers. Maybe in 50-100 years, and most of us won't live long enough to own one. Then again, one can hope...
As usual with generic press, the text is almost 90% bullshit.
1- It was not the first quantum computation : they have done things with NMR before.
2- These qubits do not live 1000 times longer than previous ones at all. They don't even live longer than the first superconducting qubits (merely 100 times), and they live shorter than other types of qubits like cold atoms.
3- These are not "aluminum atoms grouped together to form qubits", these are superconducting circuits which are made from aluminum and which act like qubits.
4- Blake Johnson is the 5th author in this paper. Leonardo Di Carlo is the 1st one.
5- The picture is NOT Blake Johnson.
Go read the paper before publishing a news like this :
http://arxiv.org/abs/0903.2030
Sorry
point 2 should read : "They don't even live 1000 times longer than the first superconducting qubits."
A really good example of http://www.phdcomics.com/comics/archive.php?comicid=1174
Not a fair comparison, anything last longer than a xbox.
Too much hair, but nice!
that's what she said
honestly, first time I've used that.. on here.
Is there a speed benefit to quantum computing? I mean, the way processor manufactures are dishing out quad-core and octo-core (?) processors with more than enough speed to handle any gaming, is it really necessary to go quantum?
If what I've heard about quantum computing is true then yes there is a huge speed benefit. Quantum computers at their base level don't use binary, that is why they will, in the long run, out preform regular computers. The problem is that even if we manage to develop a good quantum processor, computers will basically have to be reinvented to use them. All the same, when they come out and I'm 50 I might just be waiting in line to get one.
NOOOO!! Quantum Leap was my favorite show, don't ruin it with Scott's pic.
What are people gonna think when they see that image as I scroll down the main page?
The people are losing their moral while becoming modern. The society needs to be attentive that moral values. Well things needs to be modernized but keeping intact with moral values.foreclosure auctions
Well, it’s shocking and needed an immediate attention to sort out at the earliest.
