The notion that quantum mechanics is associated with inherent chance in the universe thus explaining free will is itself problematic.
There is no chance in the equations of quantum mechanics as the equations are fully deterministic. The probabilities appear only when we try to explain interaction of classical systems with quantum ones. Traditional explanation is that those probabilities are inherent to the world. But this rise the question how this can be as there is no in reality classical systems, everything is quantum with deterministic equations. So more natural interpretation is that at classical level the system looses access to some information about global properties of the system and probabilities are just a natural consequence of this.
- eigenket 5y agoIf you take this reasoning seriously you get the Everettian / "many worlds" interpretation of quantum mechanics. If a human experimenter is treated as a fundamentally quantum object then they end up entangled with the particle they're measuring. This is (to me) a highly appealing model for what is going on, but we still don't really know how to go from this viewpoint to what we observe in experiments, which is the Born rule.
- _0w8t 5y agoThe topic of appearance of a classical objects in the quantum world is far from settled. My favorite hypothesis is that when an object is entangled with too many particles in the Universe that sort of cancels interference patterns leading to classical world. This avoids the need for multi-world or similar hypothesis.
