Two teams of physicists have stored a single photon of light |
Photons create primitive quantum network (Dec 7)
http://physicsweb.org/article/news/9/12/5
Two teams of physicists have stored a single photon of light in an
atomic assembly, transferred it to another atomic cloud and then
retrieved it again -- all without significantly losing the photon's
quantum character. The results are the first demonstration of a simple
quantum communication or computation network, which stores and processes
information using atoms and photons. Meanwhile, a third research group
has shown that a stored atomic state can be transferred to an
"entangled" state of light.

....and all achieved while photon (light) was at "c"
right???????????????

You never could understand "in a vacuum" could you, Greenfield?

"Using lasers and electromagnetic traps, Matthew Eisaman of Harvard
University and colleagues, and independently, Alex Kuzmich and
co-workers at Georgia Institute of Technology, created a single photon
in one atomic ensemble..."
The alchemists of the 17th century would laugh to death reading this.
Deception in sc ience has gone too far with peoples tax money...

they say
'without significant changes'
the first question that comes to my mind
and seems to me *very important * is :
if not significantly important than
what * is* (or are) after all -
'the not significant'
changes??!!
TIA
