You're smart enough to see they can be the same thing,
regardless of what you call them.

A quantum (entangled) link automatically comes with
cryptographics as an optional extra.

Basic set-up is a source of entangled photons (they come in
pairs) plus at least two 'receivers' - which can be telescopes
fitted with 'detectors' or demodulators').

As a result of their experiment ESA now knows you can probably
have two telescopes say sixty light-years apart and use a mid-
way star as a source of entangled photons - stars generate them
(in pairs) for free.

The beauty of such a quantum-link is that one terminal can
'modulate' received photons and instantly the other terminal -
 sixty light years away - can 'read' the change.

Of course if you wanted two-way real-time conversation you'll
need a slightly different set-up, involving two separated mid-
way stars.

However broadcast is simplicity itself, and, given the sudden
huge expansion of the Drake Equation, it's almost certainly
permeating our galaxy at this time.

And we can do most of it (rather crudely) right now. The trick
will be tweaking our 'demodulator' to detect all potential
signaling.  As always 'sensitivity', 'selectivity' and 'mode'
will be the big challenges.

I suspect that's being worked on right now - would you want to

And, just thinking about this - if astronomers focused on a star
at the 'edge of the universe' (the visible universe that is)
there are some even more intriguing implications.
