The theory reminds me of the old 1956 Robert Heinlein novel, _Time for the Stars._

A series of low-tech torchships built by the Long Range Foundation is sent out to explore the nearby systems, using the conceit that telepathic twins and triplets (and their attuned progeny) can communicate “almost instantaneously” across the vast distances between Earth and the accelerating ships.

The torchship the protagonist is assigned to is eventually recovered by a technologically more advanced LRF starship from Earth.

That's the basis for quantum entanglement communications..................
