This is something that I had not been aware of until recently. There have been several recent experiments that demonstrate the "spooky action" is real. Physics is stranger than fiction.
For non-physicists (like me), in a nutshell it works like this:
Pairs of electrons are created by various methods that are "entangled". The spin of one electron will always be the opposite of the other one by some kind of conservation of spin law. If the spin of one electron is changed, the spin of the other one will also change to preserve this conservation. The strange thing is this will still happen no matter how far apart the two entangled electrons are. Even across a galaxy. Einstein called this "spooky action at a distance" and did not believe it was possible, though predicted by his mathematical equations.
The implication is there may be a way to use this phenomenon to communicate. Not only does it work over great distances, but should also work under the ocean, underground, anywhere. Also, since the effect is confined to the entangled pair of electrons, there would be no way to eavesdrop on the message, making it totally secure. You can bet the military is working on this.
The other strange thing is the interaction between the entangled pairs seems to happen instantaneously, or at least more than 10,000 times faster than light.
There are still some practical barriers to exploiting this, but it appears to be getting closer to practicality.
Here are a few articles on it.
