I assume they wanted messages to get there in under 50 years.

I'm a bit confused. What are they sending over the wire exactly? I thought the whole point of quantum communication is you use entanglement to instantly send from point A to point B, and there is no wire?

Entanglement doesn’t allow instant communication, you can’t beat the speed of light, and you still need a communication channel. Instead, entanglement is used to prevent undetected eavesdropping on the communication: https://en.wikipedia.org/wiki/Quantum_network#Secure_communi...

Halas, entanglement cannot be used for "instantaneous communications whatever the distance". This is a common misconception.

Interesting. They send the classic IP packet just before the quantum data. So they could theoretically route it without disturbing the quantum data.
The experiment just used a point to point connection between two nodes, but using standard fibre optic cabling. You would need their Q chip in every place the data gets routed to actually use it in the wider world.
