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.
