Kinda cool!

They should just make gamma ray drives.

i'd love to see what happens when you scratch the disc.

newscientist is the best science magazine out there. i love reading it.

cool

thats some cool $hit man

Wait wait wait!

They're entangling photons and all we care about is CD media capacity?

If they've gotten to 4 entangled photons, where is the limit?

What would be the characteristics of a 100 photon entanglement? Does this energy react with matter? Is there anyway to store this? What kind of sensing mechanisms are they using to see this reaction? If a source (like a light bulb) was emitting entangled photons, what would it look like to us - could we tell the difference?

woah! with this incredible technology, a CD can hold 9 times as much information as a normal CD! that's 62% of the capacity of a dual layer DVD! IN THE SAME SIZE DISC!!! OMGHI2U!!!!!!111!1

:roll:

It's about the scientific breakthrough, not the fact that it might expand CD capacity. :roll:

The article used cds as an example, there is no reason it couldn't be implemented with dvd technology. The 9 times figure was an example as well, it might very well be that they are able to entangle more then 3 photons together, which would provide even greater capacity. This would still be many years off, but to slam scientific breakthroughs based on example applications of the technology that people today can comprehend is a bit short sighted.
