Note that, contrary to popular understanding, it isn't even established that quantum mechanics is indeterminate or not subject to strict cause-and-effect.
It's indeterminate according to the mainstream Copenhagen interpretation, but de Broglie–Bohm theory [1] ("pilot wave theory") is an interpretation that is entirely deterministic, and its assumptions result in exactly the same final equations as the Copenhagen one. But every particle always has a definite position+momentum and there's no notion of wave collapse or philosophical trickiness of what constitutes an "observer". For more on the historical reasons why Copenhagen became mainstream and de Broglie-Bohm didn't, see [2].
