Quantum Communications

Researchers have sent a cryptographic key 144km (~90 miles) using spooky interaction between entangled quantum particles. This could enable instantaneous communications across the vastness of space.

quantum entanglement does not imply faster than light communication, despite much science fiction indicating otherwise.

True it may not be faster than light (I am not a physicists), but it is still conceptually iinstantaneous and could be really usefull.

No it isn't.

Yes it is. (couldn't resist.) No it isn't instantaneous or really useful?

Look if I have two entanglemented particles and I send one off with my buddy 12 parsecs away and I send a red light past it, as your article suggests, he will receive the red light signal 12 parsecs away, immediately. How is that not instaneous and useful?

Maybe I am missing something.
