Question about entanglement and spacetime

[SchrodingersRat]

Hi everyone, this is my first post.

As anyone interested in physics I am somewhat familiar with the concept of entanglement. Also I have read that contrary to what most people think about this phenomenon, the particles involved are not always exactly synchronized but one can actually seem to be ahead of the other in time (time in the sense of what you measure with a clock). This would be hard to explain in a Newtonian-like formulation of physics but as they say this is not necessarily a problem with GR.

A question I have thought about regarding this, and one I am sure someone would have come up with an experiment to test, is how this effect changes with distance. That is, does the degree of de-synchronization compared to clocks increase linearly with distance? And are there other factors that can affect this behavior?

Also, is the de-synchronization different for every entangled particle pair or is there some form of correlation in every pair with roughly the same two positions? The first would seem to fit better with the rest of modern physics, but I my knowledge of QM is not that deep yet.

I have no idea what you mean by this. A system of particles in an entangled state is described by a single state that cannot be decomposed into a separate state for each particle.

Entangled systems are not "synchronized" as you imagine. They follow a set of rules that can be difficult to understand for the beginner. Generally: time and distance are not factors. Interaction with other quantum particles or systems is a factor. Entanglement can be full (maximal) or partial. Entanglement can occur on some bases (such as spin) but not on others (such as momentum). And entanglement can be between 2, 3, or more particles.

There are literally thousands of experiments in the canon on entanglement.
