Hello, I'm planning to do my EE of IB Diploma on quantum physics and I have a doubt concerning quantum entanglement.
I know that when you have two entangled particles say, two electrons, which spin pointing in the y-axis for example, if you measure them 45º shifted in any direction you will have (1-sin45)/2 probability of getting a photon, and the other entangled electron will have then 100% probability of getting the opposite.
Now, if I measure it trough an orthogonal axis to that one measured in the first electron, will I put in the formula (1-sin(theta))/2 the angle between the y-axis and this new direction or between the axis i used to measure the other electron and this direction, i.e. (1-sin90)/2?
