Really, this is the first one? You must be new here....

A little hint: Engadget is like a really hot diseased whore. You know she's giving you the clap and probably 9 levels of AIDS, but damn she's hot. Why do you stay with her? All she talks about is frickin Apple news! You don't know, but you do stay....you do stay...and you find yourself saying WTF a lot to the things she says....maybe it's that her being so dumb is a turn on, knowing you're so much better than her.]]>Jun 29th 2009 12:58PMhttp://www.engadget.com/2009/06/29/first-functional-quantum-processor-created-lasted-slightly-long/http://www.engadget.com/2009/06/29/first-functional-quantum-processor-created-lasted-slightly-long/Jun 29th 2009 2:31PMhttp://www.engadget.com/2009/06/29/first-functional-quantum-processor-created-lasted-slightly-long/http://www.engadget.com/2009/06/29/first-functional-quantum-processor-created-lasted-slightly-long/Jun 29th 2009 3:33PMhttp://www.engadget.com/2009/06/29/first-functional-quantum-processor-created-lasted-slightly-long/http://www.engadget.com/2009/06/29/first-functional-quantum-processor-created-lasted-slightly-long/

Anyway, I'll give you the benefit of the doubt and imagine that you really are interested in physics and not just some awkward internet type ...

The NMR people have been doing computation for a long time now on systems with more than two bits. There was a famous paper by Ike Chuang in 2001 that implemented a real search algorithm on an NMR quantum computer. http://dx.doi.org/10.1038%2F414883a . I'm pretty sure there were others before that with smaller computations but off the top of my head I can't point you to links. Nobody has figured out how to scale NMR beyond a few bits, for various pretty fundamental reasons.

Looking to other technologies that can get round this limitation, the leader is probably strings of trapped, laser cooled ions. There are two powerhouse groups: Rainer Blatt's group in Innsbruck , and the group of Dave Wineland at NIST (http://tf.nist.gov/ion/qucomp/papers.htm). They've both managed to entangle long strings of ions (8 I think is the record). There's a review here http://tf.nist.gov/general/pdf/2284.pdf .

Coherence times for trapped ions are vastly longer than those for solid state systems, including the one reported above. Amazingly, optical coherences of greater than one second have been observed in these systems by encoding the q-bit in a dechorence free subspace of a pair of ions (see below). Hyperfine coherences can be much longer than this.]]>Jun 29th 2009 2:41PMhttp://www.engadget.com/2009/06/29/first-functional-quantum-processor-created-lasted-slightly-long/http://www.engadget.com/2009/06/29/first-functional-quantum-processor-created-lasted-slightly-long/http://heart-c704.uibk.ac.at/publications/papers/prl04_roos.pdf
