Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Quantum entanglement exhibits non-local correlations, but standard quantum mechanics and relativity together prohibit using it for faster-than-light communication.

The analysis

The retrieved papers and established physics principles demonstrate that while quantum entanglement involves non-locality and spooky action at a distance, it is strictly bound by the no-signaling theorem, preventing any faster-than-light communication.
