After reading this and so many other articles on so many sciencific topics in physorg.com I"m inclined to think that this has to be a brave new era [in the best sense of the term] in the development of all scientific endeavor first, and by extension, of the human mind. So many breakthroughs are happening in so many areas that shed light on old problems [while creating new ones] that it"s hard to avoid the impression that the people involved in this enterprise must experience a sense of giddy exhilaration at the possibilities opening up every day to those in a position to understand them and make a contribution to them.
I expect with further research that it is NOT a re-creation of the original photon(s). Simply a way of transfering the amplitude and phase of a light pulse (or a photon) into an environment that enables the emission of a NEW photon that has corresponding attributes to the original input. It is nonsense to suggest that the ORIGINAL is re-created.
Hi All,
I find this phenomenon a great vindication of the concept that light and matter are just two different spin states. Light is a boson and matter are fermions... there are laws which connect one with the other. Bright Matter Solitons are pseudo-particles and this may carry information in the form of qubits from one point in space to another. Of course the integrity of this process may be very finely balanced but I think it is possible to transfer the qubit without loss. It seems plausible that the Bose Einstein Condensate is transferring induced Orbital Angular Momentum between points. A suitable "holographic interference defect" could be used to produce a "doughnut field" in the BEC for the light to be "twisted" into what looks remarkably like a "smoke ring". A Holographic Defect may look something like this...
The BEC slows the light and converts it to a pseudo-fermion by adding the spin to the co-moving photons as they pass the defect.

Obviously this is an "adaption" of a concept used elsewhere. This is now "partially" a matter wave. The defects also carry "topological charge" and you can read about these phenomena here...
Light Beams in High-Order Modes
This phenomenon has been attempted before (as you can see this is not a new idea but perhaps the first successful attempt)...
This is not the same experiment but it is "instructive".
Have a look here on Taco Visser's Homepage...
Taco Visser Homepage
Taco Visser's Journal Page
Look up Optical Vortexes and underspecified Null Electromagnetic Fields and the branch of Physics called "Singular Optics".
The optical equivalent to Falaco Solitons.
If you are "really interested" look up this thread that has been progressing for some time... Problem with the two slit experiment, Observing later
Cheers

MAKING BOSONS ACT LIKE FERMIONS.
In what would represent an unprecedented manipulation of matter, physicists in Germany and Austria have proposed ways of making bosons, one of the two major classes of matter, act like fermions, the other kind of matter. Fermions (such as electrons) obey the Pauli exclusion principle: If you put multiple electrons in a box, they all must differ from each other in some way, for example by being in a different place or having a different value of a quantum property such as spin.
Bosons (such as photons and the hydrogen atom) have no such restrictions: a limitless number of them can be in the identical quantum state. Physics is replete with examples of making the fussy fermions behave like the more easygoing bosons, thanks to the phenomena of superconductivity and superfluidity. Causing fermions to pair up, as they do in superconductors, gives the pairs the same key properties as bosons, and so they act just like bosons.
But the reverse--making the normally undiscriminating bosons act like picky fermions--has never been done before. Now, researchers (Belen Paredes, Max Planck Institute for Quantum Optics, Belen.Paredes@mpq.mpg.de) have a couple of proposals for accomplishing this. One way, they suggest, would be to rotate a Bose-Einstein condensate. At rest, the BEC has several different low-energy levels due to different possible values of angular momentum in the atoms. However, rotating the BEC at just the right rate causes these levels to become equal to one another in energy since the rotation will cancel out the energy gains due to angular momentum. All stuck in the low-energy well, the atoms would be forced to minimize their repulsions with one another, and they'd do this by assuming slightly different values of angular momentum, thereby acting like fermions. Rotating BECs is now possible with lasers or mechanical devices. But to observe "fermionization" in BECs with currently obtainable rotation speeds, researchers would need to create a BEC with only a handful of atoms, say 5, instead of the typical 10,000 or so. But in case this turns out to be infeasible, the researchers have another proposal: rotate an optical lattice, a light-based web of atom traps, containing 5 atoms in each trap. Such a situation is experimentally possible and could produce a stronger signal than that from a single BEC.

Its a fallacy that a conversion between light and matter occurs. The experiment shows only that the information that describes the original light can be transmiited by a travelling matter wave through a BEC and subsequently the information can be used to generate light that has properties similar to the original input. To suggest that light to matter conversion occurs is fantasy and poor science.

You may ask where the original light of the universe came from. Original matter had to radiate original light. Light goes in and out of matter all of the time.
An absorbed photon is as said: never re-created. Totally new radiation is produced at emission.

The conversion process from light to a fermionic state and then back again is possible theoretically since qubits can be transferred to other particles from light and then back to light in laboratory experiments already. It seems to me this qubit operation completely reconstitute the original photons if the qubit is returned to the "reconstituted" photons from their fermionic "intermediate" particle state ... transferred intact back to the "original" photon packet regardless of that intermediate state. The only difference being that instead of transferring the qubit from one photon to another photon it is simply transferred back to the "original photon" through the "magic" of "slow light". Now does this early experiment do this? I can't say but refinements may indeed produce this effect. Is the photon the same as the one that went in? As far as science knows it must be if the two/three states are "entangled". Maybe even chickens can travel like this too... he he he! It is simply a new form of "slow" quantum teleportation.
Plain English Version... Light beam carrying information goes in one side, gets converted to a pseudo-particle stream and travels slowly across a space and then converted back to light... and the original information encoded on that beam will be possible to be decoded off it at the other side. This is duplicating previous work by Zellinger with a "twist".
Cheers
WOW! First light to matter then returned to light, one day matter turned to light and then returned to matter. WOW! Beam me up Scotty!

Hi Nick, bluehigh, 3nexxio6 et al,
Here are some cross references based on the original story found here at Physorg...
Exchange of light and matter: PhysOrg
Here is where the rest of the story has been originally coming from...
Light and matter united: Opens the way to new computers and communication systems: Harvard
Here is one place where it appears in the Media...
Physicists stop light, then restart it: ABC
Picture of Lene Hau and the story of how her "holographic process" works above.
I think the Harvard story suggests very strongly that they have been able to retain the original qubit. This means a total reconstruction of the original light with its full load of information.
Cheers

This is definitely amazing stuff.
A couple of questions come to mind.
How to cleanly separate the two different BEC clouds? There can't be vacuum in between, must be non-condensate instead. The 'light' must travel at speed of sound during this point.
The other thing is why slow down light at all for communication? Since it is really the speed of light that makes it attractive.

Physics Web described some more detail: http://physicsweb.org/articles/news/11/2/7/1
It seems there is transfer of atoms from one BEC cloud to the other.

Einstein General relativity fails, therefore.
William J. Cromie doesn't know what he's talking about.
When two systems, of which we know the states by their respective representatives, enter into temporary physical interaction due to known forces between them, and when after a time of mutual influence the systems separate again, then they can no longer be described in the same way as before by endowing each of them with a representative of its own. I would not call that one but rather the characteristic trait of quantum mechanics, the one that enforces its entire departure from classical lines of thought. By the interaction the two representatives [the quantum states] have become entangled.
Entangled Particle Holographics will be the name given to this hallmark discovery by Michael E. Thomas in which the event history of optical entangled ferroelectric molecules is continuously emitted (broadcast) non-locally and is received by and interacts with the other entangled particle pair's matter in its environment through a subtle process of exchange of quantum information. This is an extension of the known process of quantum emission/absorption and analogous to non-local quantum entanglement of the ferroelectric particle pairs matter.
Entangled Particle Holographics extends the reach of quantum physics beyond the atom and subatomic particles, not only deeper into the optical media data quantum substrate, but also into the larger world of encrypted data transmission. It brings the role of information in physical theories to the same level of importance as energy itself. Entangled Particle Holographics focuses not so much on ferroelectric particles as on the relationships and dynamic exchanges between energy, matter, photons, electric fields, and information. Entangled Particle Holographics looks into four basic quantum processes, heretofore largely ignored and left unexplored by science.

Look at the equation: E=MC2. 1kg of matter = 9x10^16 joules or enough to power every car in America for a week. If you could convert a photon to matter, you are going to have about a superstring's worth. bluehigh had the right idea. They merely stored a pattern in a BEC as patterns are what BEC's are all about.

Lights which have fallen down from the Void Mountain, in other words, the positive separational potential, would have gotten too much potential energy to stay as photons. When thier wavelengths become shorter than Planck length lp, photons would turn into matters which soon activate gravity forces in the negative potential valleys.

"This marks another milestone for Hau in light manipulation. In 1998, she disproved theories by Einstein and others that the speed of light in free space couldn't be changed when she slowed light from 186,000 miles a second to just 38 miles per hour."
Here I would like to draw the attention not to the fact that the speed of light is inconstant (even relativity zombies have stopped defending Einstein's false second postulate) but to the expression "disproved theories by Einstein and others". Two years ago even children were forced to sing "Divine Einstein" and shout endlessly "Einstein! Einstein! He's our man! Einstein! Einstein! He's our man! If he can't solve it, no one can!":
http://www.bnl.gov/community/Tours/TYSaDTW.asp
And now Einstein and others disproved! If this dangerous development continues, soon there will be titles like: "Absurd theories by so-called relativists condemned".

On Professor Lene Hau's light into matter and matter into light experiment, as a quantum number theorist, I think this is highly significant in cosmology. 96% of the Universe consists of dark matter and dark energy. Assumng dark matter is extremely cold, this could stop light in its path. Could this be the mechanism which causes some matter to become invisible? Is this another proof of the validity of Einstein's mass-energy equivalence principle? 
Hi all
isn't there an important fact written in this article which no one seems to be considering, quote: "It becomes squeezed into a space 50 million times smaller." end quote. she is talking of light being dramatically reduced in size. Surely if the light is being reduced so dramatically as it enters the cloud it will appear to slow down as it is being continually foreshortened.
Just a thought

Hi all again
And here's another thought based on this massive light compression
Take a large BEC into deep space and let it absorb light for billions of years Then do something which slightly warms the BEC
Wouldn't the result be a SUN (star)?
AR awaiting a massive reaction (but not a fusion one)
An additional thought here if you wanted to call the collection phase a name how about "black hole"

Hi all again again
this suggests another thought:
All these experiments use a coherent light source (laser) is this 50 million x compression possible using a non coherent source or is it only laser light that will compress?
As with most research the results pose more questions than answers assuming of course that the reasoning as a result of the experimentation is valid I have many doubts.
