The current research today, and there are millions of dollars behind it (Facebook, Amazon, Apple, Google) is the use of entanglement for quantum computers. It is not unreasonable, based on current ideas, to have a global, if not galactic and inter-galactic connected quantum computer based on entanglement. The University of Waterloo is on the vanguard of such research.
The myths about entanglement (it does not transmit information, in order to read it you have to destroy it, you can not maintain entanglement, you can not entangle enough particles to be useful, you can not manipulate the entanglement repeatedly without collapsing it) have all fallen in the last two years or so.
This research is no longer theoretical, nor pure quantum physics research. The goal is a pay-off of billions of dollars in the next decade or so in super-advanced quantum computers based on entanglement. The University of Waterloo is only one of many universities that have created entire departments to study it.
So, given such attention today by 'big money', I don't think it is unreasonable to propose it has been developed for what you want in your story. It is being taken very seriously by some very accomplished physicists.
from the University of Waterloo article
Entanglement is an extremely strong correlation that exists between
quantum particles — so strong, in fact, that two or more quantum
particles can be inextricably linked in perfect unison, even if
separated by great distances. The particles remain perfectly
correlated even if separated by great distances. The particles are so
intrinsically connected, they can be said to “dance” in instantaneous,
perfect unison, even when placed at opposite ends of the universe.
This seemingly impossible connection inspired Einstein to describe
entanglement as “spooky action at a distance.”
Einstein's "spooky action at a distance' is now reality.
Further research from China First Object Teleported from Earth to Orbit
Teleportation has become a standard operation in quantum optics labs
around the world. The technique relies on the strange phenomenon of
entanglement. This occurs when two quantum objects, such as photons,
form at the same instant and point in space and so share the same
existence. In technical terms, they are described by the same wave
Another reference from Physicists Discover the Secret of Quantum Remote Control
In recent years, however, physicists have discovered how to manipulate
quantum objects without destroying their quantum nature. The trick is
to nudge them very gently. Doing this continuously eventually produces
a significant change while preserving the quantum characteristics of
The breakthrough that Muschik and co have made is to work out how to
perform the same kind of gentle nudges on an entangled system,
something that immediately leads to quantum remote control.
