That's not how QE works as I understand it. You can observe one entangled particle and know the spin of the other one, but setting the spin of one would simply break the entanglement. It's for receiving information only, not sending.
Of course. We are talking about ansibles, a Sci-Fi communication device from Orson Scott Card's "Ender's Game" book series. They work using quantum entangled particles. In the real world, you can't "send" information between two entangled particles, but I was speculating about how it would work and its hypothetical information throughput.
I was thinking the same but couldn’t organize my thoughts to match up with the linked articles. The quantum computer can deliver new entanglements at whatever rate it wishes as long as they are below the speed of light. I don’t believe we know how to entangle particles at a distance. If you can keep particles
Le Guin’s ansibles were used for low bandwidth communication. Card expanded them to realtime immersive 3D surround. But I think that’s more fantasy than science fiction. But I believe in the later books we find out there’s some other dimension of space where things or people are wired together and that’s how his ansibles function.
