opps mayb i complexed the sentence
if we measure along axis X and then if state X goes through it shows electron spin up and if not go then it means electron spin is down.
σx|x>=+|x>
σx|-x>=-|-x>
These equations also follows for σy and σz corresponds states |y> and |z>.
if we measure along axis X then X state vector let it go which means up spin and opposite not go through which means down spin.
and also same for y and z axis.
But,
σx|u>=|d> σx|d>=|u>...
yes i got your views.. i know that we can do any additional measurement for one particle but not simultaneously...but i want to say what happened if doing measurement simultaneously for different particle in entangled condition?
why values for diffrnt like A and B whether they are entangled?? and measuring simultaneously(i heard about they correlate faster than speed of light..and its fuzzy to me..)
We know that can't measure both position and momentum simultaneously whether both are orthogonal.
If i measure position one entangled electron and momentum on other electron for single state then how Heisenberg's uncertainity princple works?? so We may know the both parameter.
