It is entirely possible that the researchers WERE doing quantum teleportation (of a photons state), but it wasn't clear from the article that they actually were, or were merely sending entangled photons.

I have a pair of shoes, one left and one right shoe.
I took one of the shoes, at random, I didn't know exactly which one, and sent this shoe to Antarctica where I have a friend. He took it up from the package and exactly the same time when he discovered which one he'd got, the right one or the left one, the information of what shoe was at my side.
Q ...[text shortened]... at the speed of light, or (b) instantaneously?
Entanglement is not more mysterious than this.
It is still mysterious as to why it happens. Even Einstein was baffled by it (spooky action at a distance) and everyone since.

Right now, it's relativity V quantum mechanics where relativity talks about big stuff like stars and people and galaxies and going close to the speed of light and how time flow changes in response to different gravity levels and the like while quantum stuff is mostly about the very small and we can't connect them as of yet. It's going to take a new Einstein I suspect, some kid who gets bullied in school because he is too smart and different doesn't want to play baseball with the guys because he is thinking so much.

Full quantum mechanics theory is already here and it fully explains entanglement and other similar quantum phenomena very well.
The problem is, quantum mechanics is NOT Newtonian mechanics and we have great difficulty wrapping our heads around it and keep trying to mould it into Newtonian mechanics.

Originally posted by sonhouseWhy? Quantum theory and relativity are pretty much good for almost everything. The really big outstanding questions are dark matter and dark energy and how big the universe is, and I am not sure those can be answered with a 'TOE'.
Well we then await the next Einstein.
We also need some sort of explanation for the fundamental particles. Although some aspects of them follow from quantum mechanics, most of their properties are found solely from experiment and the reason for their values are unknown (at least that's my understanding as a layman).
Again, the traditional 'TOE' might not answer those questions.

Need a little help to get my head around this. The Time's reports that scientists have managed to teleport an object Into space!
