I'm not a cryptographer but sat next to three of them last week, and they were unanimous that quantum internet is a giant boondoggle to keep university researchers happily employed.
It has close to zero relevance for key distribution problems in the real world, as they see it.
Sure, if you have all day to share state you can either share it securely or know it's been compromised, and then.. what? What's your key renewal cycle to key lifetime looking like?
There aren't that many contexts for mass cryptography where the central problem is fixed by this method.
