The square root of the probability, 6
There is no wave function collapse.
For example, in the double-slit experiment, with-detector and without-detector are actually two different physics systems. Different experimental setups provide different probability distributions, encoded in the wave functions. So different experimental setups result in different wave functions.
That is the key to understanding strange quantum phenomena such as EPR. A classical system has consistent results is no magic.
You create either a system with a detector or a system without a detector. With a detector, it will have only distinguishable-at-least-in-definition states, aka classical states. A system with only classical states is a classical system. Then, why so shocked when a classical system has consistent results?
Quantum mechanics is “strange”, but not “that strange”. It is not so strange that it is unexplainable.
