Or so they say has been overcome:

I'd guess we are 20 or more years from seeing anything like that for personal use.

I just had to post a reply here...not that anyone here knows jack about what the heck the article is talking about and what relevance it has to the price of tea in China lol...jk...just didn't want ya to think no one read the link. :doh:

Its like the holy grail in computing. Sometimes I feel like no one knows where we are trying to go in the future and that statement confirms it, so let me enlighten you! :D

Only problem with Quantum computers - it will make all forms of encryption obsolete over night - so no one will be able to hide anything! Oh well - open up your bank records I guess since no one will be able to hide the data.

A quantum computer is any device for computation (http://en.wikipedia.org/wiki/Computation) that makes direct use of distinctively quantum mechanical (http://en.wikipedia.org/wiki/Quantum_mechanical) phenomena (http://en.wikipedia.org/wiki/Phenomena), such as superposition (http://en.wikipedia.org/wiki/Quantum_superposition) and entanglement (http://en.wikipedia.org/wiki/Quantum_entanglement), to perform operations on data. In a classical (or conventional) computer, the amount of data (http://en.wikipedia.org/wiki/Data) is measured by bits (http://en.wikipedia.org/wiki/Bits); in a quantum computer, the data is measured by qubits (http://en.wikipedia.org/wiki/Qubit). The basic principle of quantum computation is that the quantum properties of particles can be used to represent and structure data, and that quantum mechanisms can be devised and built to perform operations (http://en.wikipedia.org/wiki/Instruction_%28computer_science%29) with these data.[1] (http://en.wikipedia.org/wiki/Quantum_computing#_note-0)

(http://en.wikipedia.org/wiki/Quantum_computing#_note-0)
Though quantum computing is still in its infancy, experiments have been carried out in which quantum computational operations were executed on a very small number of qubits (http://en.wikipedia.org/wiki/Qubit). Research in both theoretical and practical areas continues at a frantic pace, and many national government and military funding agencies support quantum computing research to develop quantum computers for both civilian and national security purposes, such as cryptanalysis (http://en.wikipedia.org/wiki/Cryptanalysis).[2] (http://en.wikipedia.org/wiki/Quantum_computing#_note-1) (See Timeline of quantum computing (http://en.wikipedia.org/wiki/Timeline_of_quantum_computing) for details on current and past progress.)


It is widely believed that if large-scale quantum computers can be built, they will be able to solve certain problems exponentially faster than any classical computer. Quantum computers are different from other computers (http://en.wikipedia.org/wiki/Computers) such as DNA computers (http://en.wikipedia.org/wiki/DNA_computing) and computers based on transistors (http://en.wikipedia.org/wiki/Transistor), even though these may ultimately use some kind of quantum mechanical effect (for example covalent bonds (http://en.wikipedia.org/wiki/Covalent_bond)). Some computing architectures such as optical computers (http://en.wikipedia.org/wiki/Optical_computer) may use classical superposition of electromagnetic waves, but without some specifically quantum mechanical resource such as entanglement (http://en.wikipedia.org/wiki/Quantum_entanglement), they do not share the potential for computational speed-up of quantum computers.
