Cause and effect and quantum field theory

[arupel]

Quantum mechanics replaces the classical concept of cause and effect with probabilities. The best explanation: it just is.

While the Heisenberg Uncertainty Principles hold in quantum field theory does QFT offer a different interpretation to this concept? Or at least mitigate some of the damage done to it.

QM doesn't replace. It refines. Different matter.
And I don't see any damage whatsoever, neither in QM nor in QFT that builds on QM.

Classical relativity is a theory of local causality.

This is no longer true in relativistic QFT, which is incompatible with local causality. What is common to both classical and quantum relativity is that information cannot be communicated faster than light.

 

[A. Neumaier]

This is no longer true in relativistic QFT, which is incompatible with local causality.

This is not true. Local causality is classically embodied in the locality of the Lagrangian density and the dispersion relations for scattering, and both still hold in relativistic QFT. Nonlocal correlations as demonstrated by Bell inequalities have nothing to do with causality violations.
