Flawed Diamonds May Be the Key to Quantum Computing

A new process for creating qubits using flawed diamonds and lasers could lead to quantum computers and impossible-to-hack networks.

As it turns out, the most useful diamonds are the kind that nobody wants, as a new way of manipulating nitrogen atoms inside of flawed diamonds may allow for large scale, room temperature quantum computers.

"Oddly enough, perfection may not be the way to go," said the University of California, Santa Barbara's David Awschalom. "We want to build in defects."

The difference between quantum and normal computing is the number of different states each can utilize. In traditional computing, the smallest form of information is the bit, which can represent either a 1 or a 0, while a qubit, the unit used for quantum computing, can represent a 1, a 0, or both at the same time.

Awschalom's new technique uses diamonds that have been flawed by the inclusion of nitrogen in their carbon matrices. When a nitrogen atom lies next to an empty space in the carbon matrix, it fills it by putting one of its electrons in that spot. By playing with the "spin" of the the nitrogen atom and electron, the pair effectively becomes a stable qubit, capable of lasting much longer at room temperature than other forms of creating qubits, which are often very unstable and require temperatures near absolute zero.

The spins of the particles may be measured and changed with lasers, and can be changed at about the same speed as a traditional computer can write information to a stick of RAM. The qubit only exists for seconds at best, but in the realm of computing, that can be more than enough time to perform some extreme calculations.

Another use of Awschalom's diamond qubits might be using them as quantum repeaters. Currently, quantum networks can be created by "entangling" particles, which then can transmit secure data over several kilometers via quantum encryption. Using chips of diamond in repeaters could significantly extend the range of these networks of impossible-to-decrypt information.

Room temperature quantum computers and unhackable networks might sound a bit far-fetched and futuristic, and that's because they are. Yet here we are, on the verge of their existence.

Isn't living in the future fun?

QUANTUM COMPUTERS FUCK YES.

Sorry, but I've been wanting a reason to shout that for a long time. Quantum computers are one of those things on my list of "Amazing things in the future that I want to see before I die."

I'll take two futures, please. :)

I can already see it now; peoples computers being stolen... for diamonds. Heists of armored trucks just so Anonomous can build personal Quantum Computers. Movies, popularizing these feats!

I like. :)

Impossible-to-hack now?

Yeah, no more so than current ones.

My brain just imploded.

Now diamonds are a nerd's best friend as well!

Fappy:
My brain just imploded.

We can just replace it with a Quantum Computer :D

I would not guess this development would reach The Escapist. This is most impressive.

I tried to find a way to fit this into the article, but I just couldn't do it. Instead, I shall grace the comments section with it.

"The Computer is now Diamonds!"

I heartily approve of your juxtapositions of serious and funny.

Of course, what do you do with a 30 Terabyte Quantum Harddrive after you've downloaded everything on Steam and a few specialist interest videos? And who's gonna be the first to put Bejeweled on diamonds?

I see they bypassed the Schlock Mercenary-noted naming problem for the "qubit"... I wonder how the move to this new system of computing will happen - a port of current software, or brand new development?

You proceed to download the internet.

ALL of it.

They can actually make diamonds, so stealing them won't be as much of an issue

http://en.wikipedia.org/wiki/Synthetic_diamond

also 80% of all diamonds mined are not suitable for jewelry, so the price of diamonds use in industrial applications are a lot lower, since there is 4 times the supply.

http://en.wikipedia.org/wiki/Diamonds#Industrial_uses

At this rate, I expect the discovery of modifiable DNA to happen in the next 2 years. Japan would go nuts over that.

In traditional computing, the smallest form of information is the bit, which can represent either a 1 or a 0, while a qubit, the unit used for quantum computing, can represent a 1, a 0, or both at the same time.

I'll go ahead and come up with a name for this new third state... "Two".

C'mon, future, catch the fuck up! I want my sodding jetpacks!

insanelich:
Impossible-to-hack now?

Yeah, no more so than current ones.

Yeah, cause they're still built by people.

Now for the encryption side... most references I've seen to quantum encryption are actually in reference to encoding.

(And don't forget about the speculation that quantum computing will allow anything to be decrypted immediately.)

Think schrodinger's cat instead of numeracy :P. The third state isn't a unique, distinct thing but rather both of the possible states occuring at the same time on the same bit.

Hmm...that's not too new, though...I held a presentation on that topic some two years ago at my university...

I'm not sure what this all means but I can't wait to see it implemented into the next generation of consoles....

Industrial diamonds.

It's only kind of like what you think.

The Hungry Samurai:

Older methods of making Quantum Computers required the computer sitting in a vat of liquid helium (about -273 Celcius) in order to operate because the compounds used inside (special carbon compounds instead of microchip silicon) would not normally be electrical conductors at room temperature.
However this new discovery (the usage of Nitrogen in the carbon compounds) means that Quantum computers won't need to be as cold to operate. But it will still be a while before Quantum Computers will be able to operate at room temperature.

You'd crash trying to restart Steam.

holy shit.. DIAMOND STUDDED CONSOLES! That joke about hte PS3 being so expensive it better be diamond-studded way back in the day now makes total sense! : )

I'm sorry, I didn't really understand anything this article had to say. I was too busy laughing from opening it and finding the old spice guy holding diamonds.

Plus I don't understand any of that science at all. Hopefully they can do some really useful stuff though.

As tech goes it won't be implemented until twenty years time and they'll overprice it; considering diamonds aren't rare.

Oh fuck! Now we have to change all software and hardware APIs 'cause the fancy shmancy Quantum computer ain't backward compatible!

Oh well, at least when the consoles finally catch up with advanced multi-core processors, we can flaunt our quantum computers at them! ;)

Host a 500 player Half Life 3 Deathmatch with your quantum processor, duh?

gigastar:

My simpleton reply; So, now that computers are diamonds how much will it cost me to upgrade so I can play Crysis 3? Also, does this mean Africa will finally become more relevant to the computing industry?

I doubt we'd ever get our Jetpacks because the Porn industry would take over Quantum Computing.

It will be the end of life as we know it.

And it will be glorious.

With this and graphene, carbon computers look like a way to go. Im looking forward for mobile phones as fast as todays supercomputers.

Sounds cool but i don't understand the impossible to hack networks. If the intended recipient is capable of decrypting the message, what is stopping a hacker from decrypting it using the same method?

Ill take one future, over easy, with a side of freaking sweet, please...

Ellen of Kitten:

Oh hell, I didnt think of it first...

Nothing is unhackable.

Nothing.

Edit: First thought when I stopped to not kneejerk react is that touting it as "unhackable" makes it sound like the Titanic of computers.

Amazing. Science, how I love you. You might hate me, but I love you so.

I wonder what the limiting factor in the power would be. Perhaps the problem with the size of the diamonds. After all, the nitrogen is an *impurity*. They'd have to space out the N enough for it to interact with the C properly, which means that the diamonds would be have to be *relatively* large. Hmmm... we'll see.

insanelich:

It's only impossible because there isn't any to practice on. ;) I've noticed that "impossible" and "hack" or "crack" are just challenges and fighting words to the hacking community.

"The Computer is now Diamonds!"

I came on here just to say that, but even after writing an entire article on the subject, you still couldn't resist using my joke. You just had to ruin my day.

I hope you're happy.

Eh... quantum entangled particles are pretty much completely unhackable.
