Quantum random-walk puts single atom into observable superposition of states

http://physicsworld.com/cws/article/news/39802

Single atoms have been spotted doing the quantum version of the random walk by physicists in Germany. This sighting of a "quantum walk" could help in the design of quantum search algorithms, or in the understanding of the transition from the quantum, microscopic world to the classical, macroscopic world.

Update 15 July 2009: The actual paper appears in this week's Science (pay-per-view, unfortunately). Here's a nice diagram from the article, contrasting (left) the quantum superposition with (right) one of the classicial random walks. The histograms below show their actual measurements in the two situations.

I don't understand. Can you put this in Lamen terms?
are you sure you want that in Lamen terms ? :-) See: http://en.wikipedia.org/wiki/Lamen_(magic)

And here's what my lamen looks like; I wear it whenever I'm at SLAC...

Your last name's employee?

No, that's a sample badge from our ES&H Manual, as is the dosimeter image.
I've been diagnosed with GERT too, oh wait, that's GERD never mind ;-)

How about CRS?
By the way, you look so much younger on your badge ;-)
yeah, at times ;-)
According to Kelseymh in reply to my comment, Scientist's have observed Atom's being in two places at once.
