Would this be an accurate portrayal of measuring the spin of an electron with a SG detector?:
- The electron is in a superposition of spin-up and spin-down;
- Upon entering the magnetic field of the SG detector, the electron enters a superposition of an upward trajectory and a downward trajectory;
- When detected, the electron gets entangled with the detector, yielding a branch in which the detector detected the electron on the upward side, and another branch in which the detector detected the electron on the downward side;
- In case of detecting the electron on the upward side, it retroactively took the upward trajectory, and in case of detecting the electron on the downward side, it retroactively took the downward trajectory.
