- From the page: "It sounds like a headline from the spoof newspaper The Onion, but for physicists, this is actually an achievement: Two teams have stored nothing in a puff of gas and then retrieved it a split second later. Storing a strange form of vacuum builds on previous efforts in which researchers stopped light in its tracks (ScienceNOW, 22 January 2001) and may mark a significant step toward new quantum information and telecommunication technologies."

- Nothing
Most of all - there is nothing!
Our universe consist of mostly - NOTHING. Or vacuum. We are having a hard time creating vacuum - or nothing - here on this planet.
According to XineAnn a perfect nothing could be - thumbing up new stumblers. The vacuum of SU!
You Go Girl - Vacuum!
ScarySquirrel is right on!

Proving that the squeezed vacuum survived its confinement is tricky, as it's hard to measure nothing. To probe the retrieved vacuum, researchers "mixed" it with the same ordinary laser light that was used to excite the optical parametric amplifier and make the squeezed vacuum. They then observed the telltale up and down in the uncertainty in that light beam, which was effectively transferred from the resurrected vacuum.
"I'm very impressed," says physicist Alexander Kuzmich of the Georgia Institute of Technology in Atlanta. "It's a real technical achievement." The ability to store squeezed states could help pave the way to new types of quantum networks that would carry uncrackable coded messages, says Kuzmich, who in 2006 stored and retrieved a single photon. More conceptually, such experiments might help spell out the boundary between the quantum and classical realms, he says. "There is something we still don't understand about that transition."

Quantum parlor tricks, useless, but amusing.
Amusing is worthwhile for its own sake. Never mind what Innomen says.
"Nothing will come of nothing" takes on a whole new meaning (what King Lear says to Cordelia when she respond "nothing" to his show-me-how-much-you-love-me -- for those of you who are not lit geeks).
I guess I just like almost everything. I think I'll go thumbs up a bunch of new stumblers just to annoy Innomen.

- From the page: "The wave itself goes away, but the waxing and waning uncertainty remains, creating a squeezed vacuum."So what we're looking at here is the scientific equivalent of the fastest gun in the west routine, or the magic flea circus.Well, I for one don't see the fleas, because there aren't any. Occam's razor people, Use it.God I cant stand the new quantum religion.http://www.scribd.com/doc/563585/The-Lab-Coat-Effect?secret_password=4e om3s2lf5ug8Storing nothing? You cant STORE, NOTHING, there's always something, even if its merely time or space.QM fans by an large exploit semantics problems and dress them up as scientific achievement.

- Both the vacuum storage and the lights storage techniques have enormous implications.
