In sci-fi, a scene is well known: the departing spaceship keeps on board a collections of entangled particles with its peers on earth. Communications underway are realized through encoding and decoding the states of the entangled particles. This way they can communicate with command in real-time even over a vast distance, where the ship needed many years or even decades to go. It’s especially useful in battle scenarios.

- kbrkbr 2y agoBut couldn't you agree on a code in advance that does not rely on the content transmitted, but on the number of entangled particles for which the collapse takes place?
- warpspin 2y agoAnd how would you test whether the collapse has taken place? This does not work. You either measure something and thereby collapse it, or you do not touch the stuff. You cannot find out via measurement whether the other side measured already.
