European Researchers Propose Quantum Network Between Earth and ISS

New kalalau_kane writes with this tidbit from Extreme Tech: "A group of European researchers has proposed the largest quantum network yet: Between Earth and the International Space Station. Such a network would see entangled photons transmitted over a distance of 250 miles — two or three times greater than previous quantum communication experiments. Not only will this be the first quantum experiment in space, but it will allow the scientists to see if entanglement really is instantaneous over long distances, and whether it's affected by gravity."

Re:Entangled Photons?

Very few scientific advances have been made without a few Unforeseen Consequences, but that's no reason for Apprehension or Questionable Ethics so we may just need to Forget About Freeman.

Can someone please explain to me why this can't be used for instantaneous communication purposes?

QE is rather like being married. You know that whatever you decide, your partner will want to do the opposite. However, no actual communication is involved.

FTL communcation with a stick

1. Put a really long stick so that the ends reach the two points you want to communicate.
2. Push the stick from one end and it moves at the same time on the other end for instantaneous FTL communication.
3. Sell sticks to day traders.
4. Profit.
