- I need confirmation that something I've read is correct.
A SG device oriented along z-axis is used to prepare a stream of spin up particles from a randomised source. These are then passed through an x-axis SG device. If their spins were to be measured now they would be 50% left, 50% right. But instead, the two beams are recombined and passed through a third SG device which is z-aligned, like the first. The spins are then measured.
My expectation was that the second SG device would have randomised the spins, resulting in 50%/50% up/down but according to what I read, they will actually be measured 100% spin up. Is this correct?
