Hardware, Embedded Systems "Scientists have taken the next major step toward quantum computing, which will use quantum mechanics to revolutionize the way information is processed. Quantum computers will capitalize on the mind-bending properties of quantum particles to perform complex calculations that are impossible for today's traditional computers. Using high magnetic fields, Susumu Takahashi, assistant professor in the USC Dornsife College of Letters, Arts and Sciences, and his colleagues managed to suppress decoherence, which is one of the key stumbling blocks in quantum computing."

Breakthrough Inflation

Well, there's an inflation of "breakthroughs" in the media. Regular readers of the - excellent - PhysOrg site know that there is at least one article per month dealing with a "major step" or a "breakthrough" in quantum computing. In June they even reported about a commercial quantum computer ("D-Wave sells first commercial quantum computer").

xiaokj is right. There was some success with noise reduction.

I prefer to stay sceptical though, because "decoherence does not provide a mechanism for the actual wave function collapse; rather it provides a mechanism for the appearance of wavefunction collapse." [Wikipedia]
This means that decoherence - the phenomenon of transiting from the quantum realm into the non-quantum classical realm of physics - is not yet really understood.
