Inside each sphere, blue shows the directions where a measurement leans up and violet where it leans down. A holds a state it need not know, and one half of a pair like Study 069's. It measures its two spins together. The state at A is gone, and one of four results appears, each with the same odds. Only those two bits travel, no faster than light. Until they arrive, B's spin still reads 50/50 on any axis. The bits say which of four points B holds, and B makes the matching half turn. All four results end on the same state. No copy was made, and the pair is used up.
