Dear PF Forum,
I have a question regarding Quantum Entanglement.
I don't know much about QE, but there's something that I want to know.
Two particles are entangled.
Blue line is the world line of Particle A
See Pic 02
Particle B travels according to Green line.
And at E1 Particle B's spin is changed (is that how we say it in QM?) so the "change" is reflected in Particle A, right.
A: Is it true that E1's "now" is at E2, according to SR?
Now Particle B accelerates a little so its word line is the Red Line. See Pic 02
And at E3 Particle B's spin is changed, now the change (Pic 03) is reflected at E2
B: Is it true that E3's "now" is at E2 ,according to SR?
C: Can, at E2, particle A is changed according to two different events?
Thank you very much
