Are quantum effects deterministic?
Quantum mechanics is non deterministic of actual measurements even in a gedanken experiment because of the Heisenberg Uncertainty Principle, which in the operator representation appears as non commuting operators.
Is the universe fundamentally deterministic?
The quantum universe is fundamentally probabilistic, unlike the deterministic universe described by classical physics. Einstein believed that the universe and its laws must be strictly deterministic. He felt that there could be no role for probability or chance, in nature’s foundation.
Can free will exist in a deterministic universe?
If determinism is true, then all of a person’s choices are caused by events and facts outside their control. So, if everything someone does is caused by events and facts outside their control, then they cannot be the ultimate cause of their actions. Therefore, they cannot have free will.
Is quantum physics deterministic or deterministic?
Quantum physics is perfectly deterministic ! But it is another kind of determinism: it is not on an individual basis i.e a “local determinism” like in classical physics (for just a single specific experiment). The determinism of quantum physics is global or statistical.
What is indeterminism in quantum mechanics?
Indeterminism in Quantum Mechanics is given by another “evolution” that the wavefunction may experience: wavefunction collapse. This is the source of indeterminism in Quantum Mechanics, and is a mechanism that is still not well understood at a fundamental level (this is often called as “Measurement Problem”).
What is the difference between local and global determinism in quantum physics?
The difference between the “local” determinism of classical physics and the “global” determinism of quantum physics is that in the quantum realm, our notion of individual doesn’t exist. Only exist the notion of collective. or global. Exactly as in the classical realm doesn’t exist the notion of global but just local or individual.
What is the problem with quantum mechanics?
The problem is in the interface between quantum and classical ideas. First of all, it isn’t that QM isn’t deterministic, strictly speaking. It’s that when you try to interpret a result in terms of classical physics, you have to give up determinism or realism or both.
