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.
Probably used freaking IPv4.
I assume they wanted messages to get there in under 50 years.
I <3 all of this.
