Super-powerful computers still mostly theory

Tipped by wvcaver See Profile
Quantum computing is a relatively young technology which has the potential to develop into the creation of super-powerful computers with super-fast problem-solving abilities. However, there are flaws in the technology which limit its abilities. One of the major flaws is that quantum communication can currently only be used on photon channels (like fiber optic cables) which limits the distance allowed by the communication. However, physicists believe that they have found a way to bypass this problem, expanding the potential for quantum communication. Their theoretical method combines a fiber optic cable with sending and receiving nodes and a bi-directional optical circulator to create a network that they believe will allow quantum communication to occur over long distances.

More of the same

So, this story makes the front page. Dry subject. No quotes from any of the links. Photon conductor chips ? Maybe in the Intelll Inginear forum. Moving on....

If the topic is so boring to you, why bother to leave a comment at all? Keeping an eye toward the future is never boring...

Re: More of the same

And there will be a lot of government funding in the area of quantum computing and especially quantum communications. And that is because the FBI, CIA, NSA, etc. are very interested in quantum communications over fiber because it quickly becomes known if anyone is eavesdropping on the fiber optic line and actually scrambles the communications as soon as anyone taps into the fiber optic cable.

The key to the technology is quantum cryptography -- sending messages via optic fibers, one photon at a time. As quantum states cannot be copied, users of the system will know immediately if anyone steals the information. As Huntingdon says, "If you're sending one photon at a time and one goes missing, you definitely know it." Although other similar commercial systems exist in the United States and Europe, they use filtered lasers to approximate single photos instead.

Skynet.

Wait..so is this just a super computer solving problems? Something like Folding@home?

DSLR didn't really say much about the project..just seem like they saw the news clip made up a few things to say about it and threw on the main page..bleh

The future beckons

I think this is fascinating. I'd love to come back 200 years from now to see how technology has advanced, specifically in the areas of medicine and computer tech.

Companies like IBM developing a processor that uses light pulses (See IBM Research) is very intriguing to me.

We have dual- and now quad-core processors, IBM's Cell processor, and AMD's announcement of an 8 core processor due in 2009 is very exciting.

Technology is accelerating at faster levels than it has previously, if you ask me. If I had mentioned 1TB consumer-level hard drives 6 months ago, you would've declared me to be a fruitcake. Now they're widely available (albeit quite expensive for the time being), but the point is they exist!

Flash drives are now up to 32 GB. It's enough to boggle the mind.

So bravo to BroadbandReports for passing along this story. The future looks to be compelling.

While I agree with you for the most part, I had to point out that about 6 months ago Seagate introduced a new 1TB hard drive for the consumer market. And 12 months ago Hitachi introduced the "Deskstar 7K1000" which as you can guess also had 1tb. So if anyone had called you a fruitcake, they would have been a cup of cherries short of a fruitcake themselves...

But yes, technology accelerating at an amazing pace. I never thought I'd have 4 gigs of ram, let alone 8.

Warp to the Future.

Once they get the Heisenberg Compensators developed the technology will really accelerate!

10^90 bits!

It is probably one of the most promising technology. Just look to this from wiki article:

"The number of classical bits required even to estimate the complex numbers of some quantum state grows exponentially with the number of qubits. For a 300-qubit quantum register, somewhere on the order of 10^90 classical registers are required, more than there are atoms in the observable universe".

Hopefully...

This technology will lead to the invention of the flux Capacitor! Time travel will be fun indeed.

BSOD

Can't wait to see the Microsoft OS that will choke one of these computers.

WOW

This is really fun knowing what the Quantum Era will bring

and i have to agree with the person above me.. what will Microsoft OS do to destroy one of these systems.

Re: WOW

Yeah, probably make it run like a 486. But at least it will be doing it at the speed of light..
