Non-entangling environmental noise in QM/QFT

Click For Summary
SUMMARY

The discussion centers on the existence of non-entangling environmental noise in quantum mechanics (QM) and quantum field theory (QFT). Participants argue that if such noise exists, it fundamentally contradicts the principles of quantum entanglement, suggesting that QM and QFT cannot be considered fundamental theories. The concept of non-entangling noise is described as a stochastic process that interacts with quantum systems without becoming entangled, indicating a potential non-quantum effect in nature. This raises significant implications for the validity of current quantum theories.

PREREQUISITES

Does non-entangling environmental noise actually exist? The existence of such a thing seems to be fundamentally inconsistent with the properties of quantum entanglement.

It seems to me that if non-entangling environmental noise does exist, then standard QM - or QFT for that matter - automatically cannot be seen as a fundamental theory anymore.

What would this even mean?
 
Environmental noise, e.g. some stochastic process within some stochastic differential equation, which only interacts with quantum systems in such a manner such that it cannot ever become entangled with the system that it is interacting with. In other words, the source of such non-entangling noise would be an intrinsically non-quantum effect occurring in nature.

The existence of such a noise source would automatically imply that quantum theory - in any of its currently accepted incarnations or formulations - is necessarily incapable of actually being a fundamental theory of physics.

NB: I'm not an experimentalist, which is why I'm asking, but this is as much an empirical question as it is a mathematical question.
