Even if quantum crypto reaches distances of 100‘000km it would still not mean we can use it at home I suppose, because just having one switch/router between Alice and Bob would break the scheme, no?

I'm not entirely sure why this comment gets downvoted, because it's spot on. QC is impractical for any real-world network, and the idea that it could ever play a role in the real-world Internet is just fantasy.

But also we don't need to. Cryptography without quantum is just fine.
