And, of course, it’s really not fundamentally deterministic. It’s fundamentally quantum indeterministic.
Which does not relate to compatibilism.
Plus QM may well be seen as deterministic.
''Wave functions - the probability waves of quantum mechanics - evolve in time according to precise mathematical roles, such as the Schrodinger equation (or its more precise relativistic counterparts, such as the Klein-Gordan equation). This informs us that
quantum determinism replaces Laplace's classical determinism Knowledge of the wave functions of all of the fundamental ingredients at some moment in time allows a ''vast enough'' [Laplace] intelligence to determine the wave functions at any prior or futures time.
Quantum determinism tells us that the
probability that any particular event will occur at some chosen time in the future is fully determined by knowledge of the wave function at any prior time.
The probabilistic aspect of quantum mechanics significantly softens Laplacian determinism by shifting inevitability from outcome-likelihoods, but the latter are fully determined within the conventional framework of quantum theory.'' From page 341 of '''The Elegant Universe''
