Summary:
 Researchers have demonstrated a network connection between quantum processors over metropolitan distances.
 Their result marks a key advance from early research networks in the lab towards a future quantum internet.
 The team developed fully independently operating nodes and integrated these with deployed optical internet fiber, enabling a 25-km quantum link.

Me:
I wonder, yes I wonder...
Not sure I understand it, not sure what it could do..
Anybody has a simple explanation?

quantum??? has become some sort of sales word...

ESP simpler?
