Yes, there were, although the 'computer' is just a few atoms that communicate.

A good website on quantum mechanics: http://en.wikipedia.org/wiki/Quantum_mechanics\n\nAlso, if you are intrigued by the cosmological theory of the universe, The Life of the Cosmos by Lee Smolin is an excellent read.

The very first motherboard was built by Eiranpreet Khangura. \n\nThe original Colossus used a vast array of telephone exchange parts together with 1,500 electronic valves and was the size of a small room, weighing around a ton. This 'string and sealing wax affair' could process 5,000 characters a second to run through the many millions of possible settings for the code wheels on the Lorenz system in hours - rather than weeks. \n\nBoth machines were designed and constructed by a Post Office Research team headed by Tommy Flowers  at Dollis Hill and transported to the secret code-breaking centre at Bletchley Park, near Milton Keynes, where it was demonstrated on December 8, 1943. We have to fast forward nearly thirty years to 1972 for the arrival of the first desktop all-in-one computer, which are more familar to us today. That honour falls to the HP9830.  But unfortunately few people got to hear about it because Hewlett Packard marketed it primarily to scientists and engineers - by nature very quiet people!

The answer is a definite Maybe.\nAs for the space elevator, my understanding is that to complete one, we would need an ultrathin, ultralight, flexible material wit a tensile strength surpassing all we have now. Quantum Physics is THE tool for people who design new materials. Without using quantum physics, it would all be simply trial and error.\nTime travel is a very slippery subject and I can't comment on that. Right now we have no idea how to begin thinking about it.\nMolecular transport, as in beaming stuff the Star Trek way?\nI'd say there's a lot of problems with that, but quantum physics is the very starting point. All that happens to molecules is subject to quantum laws. Therefore I don't know if qf can bring those things abot. However, nothing else can.

Quite frankly I find it fascinating.  I haven't had the opportunity to study up as much as I'd like on the new ideas coming forth, but I would like to suggest a movie to you; it's called "What the *bleep* do we know?".  There are many credited scientists and mathematicians and other experts in their fields who discuss quantum mechanics in a way that your everyday Joe can understand.  Although a good chunk of it shows how the ideas relate back to the body/self.  Some of these ideas are portrayed in a "story" about a deaf photographer--which is an excellent idea, considering much of quantum mechanics deals with the idea of an "ultimate observer".   One warning, though; the movie does, at one point, all but mathematically dispel the notion of "God"...\n\nHope you like it!

No no in classical model of mathemetics.But in quantum logic one of these problem the factorization problem is solved by the Shor's algorithm..In fact this gave the scientist a new look for the quantum computation.

Currently not possible. Scillicon is not the most efficient but its abundance on earth is amazingly practicle. They've found ways to use nickle for example that can be 1000 times faster, but they'd have to reconstruct all the mechanism of the computer. \n\nnewscientist.com search quantum computer\n\nhttp://www.google.com/search?q=site:newscientist.com+quantum+computer

A good book is called the new quantum universe.  You'll need to give yourself a bit of time to absorb all that information.  But it contains all the basic ideas, formulations and explanations to get started

Young's double slit experiment does not PROVE that we create our own reality. However, some believe it does offer evidence that perception can affect reality. \n\nIt doesn't simply show the wave/particle duality of quantum particles. When the experiment is set up with no detectors, and a beam of light is sent through, an interference pattern is formed, as is expected wave behavior. However, if a detector is placed at either or both slits in an attempt to differentiate which slit a particular photon travels through, the difraction pattern is not achieved.\n\nThe Copenhagen interpretation takes this to mean that until the photon is detected, it exists at all points in space. In the abscence of detectors, the particle can and therefore does pass through both slits, thus arriving at the grid at the exact same time via both pathways and causing interference with itself. However, when the photon is detected by way of a physical interaction with the placed detector, the photon suddenly exists only in the point in space where it has been detected, and therefore reaches the grid via a single path and causes no interference pattern. \n\nThis does not neccessarily mean that if one chooses to see something, the necessary light waves will form to bring the vision to reality, but it does suggest that the universal reality we rely on may be based on the physical interaction of all its parts.

Actually, the answer is "yes", tho in the earliest stages.  Photon teleportation is old news.  Complete atoms have been teleported, and supposedly last year, the quantum state of an information system consisting of many atoms has been teleported, tho not yet fully verified.  In addition, there are other viable approaches to forms of teleportation, probably the next most promising involving intense gravitational fields, as from wormholes or black holes.  The fact is, there exist no limitation of physics to prevent at least several forms of teleportation - it is basically just an engineering problem, massive though it may be.  Check out wikipedia's article on the subject.

They havent yet. Not in the usefull sense. However, I know scientists are sucessfull in creating components for nanobots. They've created ultra small engines, switches, transistors, wires, etc. The tecnological hurdle as I understand it is that 'connecting' these devices are really tricky.

Don't understand your question. Did you proof read it? I bet you didn't, did you? \n\nDo you mean 'is quantum theory able to define a quantum of a quantum?'?\n\nIf so, the answer is no. A quantum is by definition the smallest step unit. The smallest unit of energy is h bar, which equals h over 2pi.

It has allready been done. Particles have been 'transported' from one local to another. It happen ed when I wrote and answered this question, \n\ninformation was teleported, as were some atomic and sub atomic elements. \nRecent developments\n\nUntil recently, scientists had been able to transport only light or single atoms over short distances (millimeters). However, it was reported in October 2006 that Professor Eugene Polzik and his team at the Niels Bohr Institute at Copenhagen University in Denmark have made a breakthrough in the field.[3] Their experiment involved the transportation of information from one macroscopic atomic object containing thousands of billions of atoms to another, located half a meter away. The technique involved the use of quantum entanglement, quantum measurement and quantum feedback. Little information is available, however, which throws suspicion over what would otherwise be a great accomplishment.\n\n[edit] Davis report\n\nIn 2001, the United States Air Force commissioned Eric W. Davis, Ph.D., FBIS, to do a scientific study of teleportation.[4] The Davis report has been very controversial due to its recommendation of further studies of p-Teleportation:\n\n    A research program improving on and expanding, or implementing novel variations of, the Chinese and Uri Geller-type experiments should be conducted in order to generate p-Teleportation phenomenon in the lab.[4]\n\nThe report (page 2) classified teleportation concepts into five sections:[4]\n\nsf-Teleportation \n    "the disembodied transport of persons or inanimate objects across space by advanced (futuristic) technological means." The report does not further define sf-Teleportation, and has no further comment on it than to dismiss it from the scope of the report. This type of teleportation could use a physical connection between the two locations, such as a wire. Using existing technology, such as the Internet, or telephone lines, could be the means for this type of teleport. However, this means it would be extremely slow, since a typical living animal is approximately equal to 600YB (yottabytes). Compression could be utilized, but would have to be effective in keeping all data intact.\n\np-Teleportation \n    "the conveyance of persons or inanimate objects by psychic means."\n\nvm-Teleportation \n    "the conveyance of persons or inanimate objects across space by altering the properties of the spacetime vacuum, or by altering the spacetime metric (geometry)." This category includes the use of wormholes for transport, and the modification of the speed of light.\n\nq-Teleportation \n    "the disembodied transport of the quantum state of a system and its correlations across space to another system, where system refers to any single or collective particles of matter or energy such as baryons (protons, neutrons, etc.), leptons (electrons, etc.), photons, atoms, ions, etc." The report explicitly includes in this category a process essentially the same as that envisioned by the fictional transporters of Star Trek. It also includes quantum teleportation by means of quantum entanglement.\n\ne-Teleportation \n    "the conveyance of persons or inanimate objects by transport through extra space dimensions or parallel universes."\n\nThe report did not investigate sf-Teleportation other than to define it. The report recommended further study in all other types of teleportation (pages 28-29, 47-49, 54, 62).\n\n[edit] Teleportation scenarios\n\nThe use of teleportation as a means of transport for humans still has considerable unresolved technical and philosophical issues, such as exactly how to record the human body sufficiently accurately and also be able to reconstruct it, and whether destroying a human in one place and recreating a copy elsewhere would provide a sufficient experience of continuity of existence. Believers in the supernatural, such as religious people, might wonder if the soul is

Two words - Quantum Computers\nIBM has one and so do many prestigous hi-tech companies\nThey are what the super-computer once was\nThey compute information in 0,1 1,0 and a super-position (I have no clue what this means) of both. Check it out for yourself. Do a google and see the amazing power of the QUANTUM COMPUTER!!!! (echo...echo...echo...)

The first "true" Bose-Einstein condensate was created by Cornell, Wieman, and co-workers at JILA on June 5, 1995.  It can be considered the fifth state of matter.

I am sure you can work out the possibilities on your computer. It is all a matter of calculating the variables.I am sure it has been done in the past.These days they just fasten electrical wires around them.

Its been done already!!!! I read a headline about a company (I'm sorry I don't remember which one) that created a robot controlled by brain waves.  WOW!
