Here's something that has always bothered me about this topic:
> That, Ritter says, could extend the application of the network even further: once two atoms are entangled, the quantum state of one depends on the quantum state of the other.
And what exactly is the benefit from that? It sounds as if now you could manipulate one of the atoms, and the other would follow suite, allowing you to transmit information.
But my understanding of quantum physics is that manipulating one atom immediately breaks up the entanglement, so no information transmitted. And this is not just a technical limitation, but a conceptual one.
Am I wrong? And if no, how would a pair of entangled atoms help us in building a communication network?
