Engineers send quantum signals with standard Internet Protocol
- Hizonner 1y agoProbably used freaking IPv4.
- YmRgtKH7cT9hxUj 1y agoI assume they wanted messages to get there in under 50 years.
- nativeit 1y agoI <3 all of this.
- sam0x17 1y agoI'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?
- layer8 1y agoEntanglement 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_communications https://en.wikipedia.org/wiki/Quantum_network#Secure_communi...
- Martin_Silenus 1y agoHalas, entanglement cannot be used for "instantaneous communications whatever the distance". This is a common misconception.
- MattPalmer1086 1y agoInteresting. 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. Still - cool proof of concept.
