Anyone who is interested. Moore's law proven right again, but for how long?

I'm curious as to when transistors get replaced with something else. Transistors can only shrink so much...

Quantum Processing (using Quantum Particles instead of transistors) is already being looked at. Not sure if anyone has figured out a working model yet, though.

If memory serves, they have found how to make the (quantum) particles spin in two axes thus far. I don't remember if they've gotten the third axis rotation just yet.

Have they figured out how, why, where and when the opposing particle is the opposite?

I couldn't stop giggling when I was told that the reason Quantum computing will be the next big thing, is because the transition of data is instantaneous, all because if we have one part of the particle, and it is negative, we know the opposing particle is positve. We just don't know how, nor where it is. :lol:

None of the big 3 (IBM, Intel, AMD) are seriously researching QP are they? I thought it was just universities at this point.

Big chip companies are keeping an eye on it, but I don't remember them doing any direct research in them just yet. They're researching materials at this point from what I've seen.

There is loads of QC and LC research ongoing - of course the big companies will not push in major dollars until it leaves the realm of pure research. Still, a lot of what's happening continues to progress incrementally. There was an article a while back about storing images as a collection of photons for an extended period of time. But we're talking decades before a realistic desktop setup that can do this is available.

QC really is a very long term project. Until that happens the major expansion will be towards multiple cores (which is just getting started - onwards to 45nm). QC will likely reach storage solutions first if I had to bet.

'Tis called quantum entanglement - when two atoms are entangled, they share a single state regardless of distance. So when you measure one, you immediately know the state of the other.
