The spooky part is that once entangled, the pair sort of act as one and anything that happens to one of the photons, affects the other. It has to do with having all of the possible outcomes encoded into the photons (by nature), in other words, every possibility is worked out before hand and then forcing one photon to become one of the possibilities forces the other to enter that possibility, because they are entangled.

The future generations of this technology could be used for deep space communication. you would probably never be able to send video footage this way... Or perhaps you could if you were using photons. But just imagining being able to transfer information from one point to another billions of miles away instantaneously? That's why I love what science does for humanity. This is quite amazing.

“Oh wow, so they like, what, teleported a chair or a banana or something?”

“Well, no, they teleported an atom”

“Oh, OK, well that’s still pretty cool.”

“Well, technically all they did was make one atom just LIKE another, they didn’t actually teleport it, per se”

“OK, you’re just screwing with me now, right?”

"Spooky" is closer to slang in English than "spukhafte" is in German, but it's a reasonable translation. Re: 4. Elissa Says:

He officially called it “spukhafte Fernwirkung”. “Spooky” is closer to slang in English than “spukhafte” is in German, but it’s a reasonable translation.

It works by entangling two objects like photons or ions" Aren't ions matter also?

Aren’t ions matter also?

I was under the impression that quantum entanglement did not allow for superluminal information exchange. I thought you can't control the state of what you observe, you can only know that it's entangled with the observation at the other end. I.e. you can't send me a specific message faster than light by manipulating entangled particles... but you can observe the particles, causing waveform collapse into a random state, and I will then see the complementary state when I observe the entangled property.
