Problem

In an EPR-type experiment, two spin-12\frac{1}{2} particles are emitted in the state ∣1,1⟩=∣+z,+z⟩|1, 1\rangle = |{+z}, {+z}\rangle A and B have their SG devices oriented along the xx axis. Determine the probabilities that the resulting measurements find the two particles in the states ∣1,1⟩x|1, 1\rangle_x, ∣1,0⟩x|1, 0\rangle_x, and ∣1,−1⟩x|1, -1\rangle_x.
