Quantum computing

[Cosimo]

I bet we'll look back at Crysis and crease our foreheads in disgust in the same way we look at a troll thread on the forums

We'll certainly remember your trolls.

Indeed, 10 qbits today but when you look at the overall time it took to come up with this, could be just a matter of a few years before there's a commercially viable option, either way very exciting news as it's finally been cracked.

Games wise oh gawd, you could probably run the matrix off the thing in years to come.

Ai anyone?

I guess the immediate role for quantum computers will be energy research and space exploration as well as massive physics calculations. I think Space travel will benefit immensely from it because if we understand more about the universe via quantum computing then we can build new technologies to bosh around in space

Among other things.

Is this the same principle as the double slit experiment? If you observe or measure the chips function will it still work? My head is sore.

Yep that's the one, from the limited reading I've done around the subject they will use the entanglement theory to allow us to see what's happening without actually observing the qbits doing the work.

So what will we do for security/encryption when these things really get scaled? Even WPA2 with a 256bit key won't be much use once the number of Qubits rises enough

WPA will be fine by the current outlined quantum cracking algorithms Well a 256-bit key would be reduced down to 128-bit which is still very on the strong side of things. It's the public key stuff that will get badly pwned e.g SSL. Yes new cryptographic methods will come along, but everything you do up to that point will be vulnerable (e.g archive the stuff and attack it later on)

i think one of the biggest benefits of this (as somebody mentioned) will be in research, scientific, medical and so on. If and when these become available, i can imagine a lot of other technological and medical breakthroughs will follow.

Hospitals would benefit a great deal from quantum computing.

We still have the unbreakable one time pad.

I'd like to think I'm reasonably knowledgeable with computers, but this lot has gone right over my head

Could anyone explain to me how this compares with say the latest i7?

It's the most adequate way of putting it lol

It has the potential capability of processing millions if not billions more bits per second.

What is that in relation to today processors then? x5 the capability or 500x?

 

[hux]

500x

 

[Marine Iguana]

Will this enable me to increase my E-peen on a massive scale

 

[andy_mk3]

500x

I'll have two.

If an i7 920 overclocked gets 69 Gigaflops (about average for one) then a Quantum computer would be something like this:

Whereas a standard transistor can perform only one operation at a time, a qubit can perform many simultaneously. Therefore a quantum computer containing the same number of transistors as an ordinary computer of today can be a million times faster. A 30-qubit quantum computer could perform as many as 10 teraflops - 10 trillion floating-point operations per second! Today's desktop computers perform gigaflops - billions of operations per second.

It will also mean a massive shift in how we talk about speed and specs of PCs of the future, we will be talking qubits!

It will be so massive that it will disappear in the horizon.

The processor will turn into a black hole and swallow us all up,will it use more than 4 gig ram though lol

Much appreciated

DON'T MENTION THAT!!!

My brain still hurts from my uni discrete coursework

Can't wait till this stuff starts coming out, just hope we don't create self replicating AI.

Oh we won't. It will create itself!

Saturday Morning Breakfast Cereal had a funny cartoon on this
