> The company says a research team has used quantum cryptography to securely send and store human genome data

Unless I'm wrong, it appears to be a "milestone" in that they sent human genome data rather some other kind of data (I'm not sure how that is significant) and no new quantum cryptography breakthrough has been achieved?

Yeah I read this the same way. The article is very vague and does not mention anything concrete at all.

It's crazy how they messed up, the original Toshiba press release is super clear and even leads with this list of key points for media to use right up top:

-New dual band stabilisation technique cancels the problem of temperature and strain fluctuations to allow long distance quantum communication

-Quantum key distribution demonstrated on fibres of record 600km length

-Significant advance towards building a global quantum internet

I don't see how the third follows from the second, wouldn't a Quantum internet that spans the globe always require point-to-point physical links between any two parties that want to trust each other?

"point-to-point" links can be circuit-switched at least, so you don't need an actual full mesh.

Why would it need to be end-point to end-point? Just have routers continuously build up entanglement with their neighbors, do entanglement swapping along packet-switched paths, and then use the entanglement to teleport via the classical internet.
