quantum computers

Anyone know much about how you would unput/output from a quantum computer, how you would program one, and how it would interact with things like cosmic rays?

Some think they'll do everything theory assumes, but I think they need to put down the sci-fi book and look at reality. In the end, I think it'll be like trying to travel faster than light--theoretically possible, but impossible in our physical universe. Just don't be disappointed if it has just a few limited applications. The science learned in pursuing it will be invaluable.

Tricky stuff. A friend of mine just transferred to Berkeley and that's his major gig, quantum computing. Only a few basic calculations can be done with it now, but if they ever have a breakthrough with it watch out. Considering the human brain may work on this quantum level consider the possibillities (speculation). We'll see.

Whoa here, now the human brain clearly has a center of sentience that exhibits the properties of--seeks love and music, generates randomness, and stores infinite quantized input (in a nonquantized way). Now except for maybe randomness, I don't see how current quantum computers are built to do this.

 

It may have to do with nonlinearity.

On the other hand, it may just have to do with complexity and using enough programming instructions (the right ones) with the right system.

But I don't want to detract from the topic. I'll let someone more familiar with quantum computers explain how they work

Quatum computers are only useful for large matrix number crunching (no not like the "Matrix" more like a massive group of numbers) they will most likely work only as a off set specility function for Super/Ultra computer of the future. They have limited practical uses and no they are not the key to sentient thought, that’s from having a self wiring, analog, unsochronized parallel processor (what the brain is)

 

More number crunching and storage = VCR that can record "everything."

Why has nobody thought of such an obvious application of increased computing power?

The problem of the VCR.

Or the limited number of hours that can be stored on digital video recorder hard drives.

When you program a VCR, what you are really doing is telling it not to record anything but a few selected programs.

What I have daydreamed about years ago, is a TV that could record "everything."

Record every channel simutaneously, for all the years that it exists.

Then rather than having to program it to record anything, I could simply make an inquiry to show me the Star Trek episode, in which [whatever] happened. It would search its database, and find the episode, if it had ever aired since the TV was hooked up to cable, satelite, antenna, or whatever. (Let's assume that the satelite tuner in built into the TV, so "every" channel could be recorded simutaneously.)

I could simply instruct the TV to display the next episode of Star Trek, Twighlight Zone, or whatever, that I haven't watched yet.

Imagine being able to watch TV, by "going back in time" and simply specifying the channel and date/time index.

Of course if Big Brother government gets ahold of such computers, what evil might it be used for? Do we want Big Brother perhaps archiving and perhaps miscontruing every word we ever said on a telephone?

And while the Internet might serve as a vast "electronic library," such a "library" is still far too fickle. Just because you can find something on a website today, doesn't mean it will still be there tomorrow, although I would like to see more websites that don't purge and change their urls to access pages, so old links wouldn't "expire." How about a computer that could contain an entire "library" in it or "save" the present state of the Internet for archival purposes?

 

Increased computing power does not equal increased storage. The quantum computing power would indeed be needed to search a huge database such as that, but storing it is a different story.

I believe that usgin the quantum processing system to build RAM would serve the purpose.

 

Just a quick point in a the right direction, Einsteins Equation of E=MC2 stated that "Mass can not travel faster than light", how ever later Even Einstein mentioned that "Information can travel faster than the speed of light".

This was talked about with the EPR (Einstein-Podolsky-Rosen) Paradox or for you laymen out there, The explaination to how subatomic particles can communicate with each other over distances, in the sense that if a truck turns a corner, all of it's particles know where they should exist, they don't just fly off in different directions.

There is also the point that light doesn't just move along one axis, with frequency alterations although distance might stay the same width & height will not.

This is where the real use of Quantum computation is unravelling the usage of manipulating the oscillations further than that of how normal SQuIDs (Semi-conducting Quantum Interference Device) work.

There are preposals to utilise Semi-conduction quantum machines (Room temperature versions), as previously thoughts were churning around the problems with super-conduction needing super-coolants due to their energy and temperature excertion.

There is anticipation into the new use of "Quibit" (pronounced Cubit) where the utilisation of atoms and there particles will replace not just processors but the storage facility also.

(Note: the human mind works on the basic of Cycles just like RAM, how ever the very nature of the cycles patterning is more organic that it's machine counterpart. None the less it means if the system stops cycling the data, it loses memory. This is why many people have suffered complete retro-active memory loss where they think they are a kid again, or don't realise they've been in a coma for a few weeks)

I mention this for AntonK, as The processor is also the storage unit.
