Aug 20, 2020 at 18:04 | comment | added | Glenn Willen | I don't have a good reference for this, but perhaps someone can expand this into a good answer by finding one? I believe the answer is "yes, subtly, depending on what you mean by 'coordinate'." See en.wikipedia.org/wiki/Quantum_game_theory for the general idea of what I'm getting at -- I believe I've read a paper showing that a pair of players with access to entangled particles have a better expected outcome in the Prisoners' Dilemma than without. But I can't find a link at the moment. | |
Aug 20, 2020 at 0:25 | comment | added | JBH | Just to make a point. Let's assume the planet in question is the Earth. Diameter = 12,742 km. Speed of light: 299,792 km/s. For the information to be transferred FTL, the transfer would need to take place in < 42.5 ms. No matter how precise the atomic clocks are, I'm not sure two humans could be trusted to check the qubit together to that level of precision. But it's an interesting question! | |

Aug 19, 2020 at 20:03 | comment | added | Mark | As a general rule of thumb, any time you see the words "quantum entanglement" and "FTL" in a question, the answer is "no". | |

Shinier title which describes the question better. This is a good question which should make the HNQ list.
