- krastanov 9y agoWhile the image is correct, your statement would be a bit misleading to novices: You can not transfer the state of the qubit over a classical channel. You need both a classical channel and entanglement. Or in other words: a bit can be send over a classical communication channel (by copying it), but to transmit a qubit (which can not be copied due to its quantum nature), you either need to carry the physical qubit over, or use entanglement together with classical communication.
- IntronExon 9y agoThe essence of the issue for many, who seem to equate entanglement with FTL is that a classical channel is required. Without that, you’re just sending noise over your quantum channel. Plus we get to keep cause and effect ordered, as a little bonus.
