Quantum Computing

[Tecnos]

In brief, Quantum Computing is the theory that computers, or more accurately, their components, have been developed to be more-or-less as small as they can be, give or take a few years of further development.

To try to put this simply:

Modern computer chips and processors rely on streams of electrons, some rely on very small streams of electrons.

If components continue to be made smaller, they will no longer rely on streams of electrons, but single electrons. Herein lies a developmental problem.

The action of electrons in a group, have a natural effect upon their neighbors, that is; their behaviour is predictable. Kind of like gravitational bodies in space, each electron (planet or star) in a series (solar system or galaxy) exerts a force or control over its neighbor. We can therefore predict it's effect and action. It is effectively 'self checked'.

The action of a single electron however is unpredictable. Essentially meaning that a barrier will be reached with the size of electronic components where they simply will stop working.

The theory of Quantum Computing proposes a hypothetical solution to this barrier.

What if?

Let's say that a calculation is so vast that it would take a Cray supercomputer a few thousand years to complete, an ideal calculation here would be: mandelbrot set to conclusion IE: xn+1 = xn2 + c (c=1 therefore extrapolated to infinity).

One application or theory of Quantum Computing would be to break the calculation into manageable chunks, move them to another plane of existence, work it out and bring the results back here. to our IS. This would render the need for a tangible computational processor irrelevant, as the calculation and for that matter, the computer hardware required to complete the calculation doesn't actually exist.

Lost?

Sorry.

The LHC is on the brink of touching on this, exploring the path that quarks take as the pop into and out of existence. the fact that something isn't there, doesn't necessarily mean that it doesn't exist.

There is sound evidence to support Quantum Computing and the underpinning 'technology', the best place to start is a book called: The Feynman Processor by G.J. Milburn 1998.

Be warned though, it can be hard work at times, especially if you are a 'maths muppet' like me.

Wikipedia is always a good foundation.....

If I remember correctly, it has the potential to use it's own energy from the electrons to power it.

Pop in and out of existence? Like the show "friends?"

[Tecnos]

Yeah.... like the band; "Men at Work"....
Vegemite sandwich indeed!

Good read tecnos, i find the possibility very interesting. Moving a calculation to another plane of existence actually blows my mind, but i saw a really really cool movie on quantum physics that explained some very interesting theories in the quantum science

[kidflash2008]

I have read about this theory too. The nanobots can be programed to fight cancers and diseases in our bodies. This would be like that movie with Raquel Welch going into a human body in that shrunken ship.
Super computers that are no bigger than a credit card and other interesting ideas. This is true Star Trek stuff, and we are on the brink of it.

Yeah, They already managed it, to make a small claculation (I think it was 3 x 5) with just 7 atmos!

Do you mean, that they can run forever with no external chargesystem? Thst would be very good for for example robots.

Possibly. Depends on how well my memory serves.
