Why do you think that these quotes imply FTL? They talk about a network allowing communication over a large distance, but they don't specify a communication speed. Why would you assume that means that it would be instantaneous/faster than light?
A more parsimonious reading of the article would assume that the author knows, and assumes you know, that FTL communication is impossible, and that the interesting aspect of the communication possible through an entangled quantum network is, as stated, its security and resilience to eavesdropping.
- finnh 11y agoThe interaction between the particles is instantaneous. There is no mention of a non-FTL communication betwixt the particles. And then there's this sentence in the same article: But since the 1970s, a series of precise experiments by physicists are increasingly erasing doubt — alternative explanations that are referred to as loopholes — that two previously entangled particles, even if separated by the width of the universe, could instantly communicate. So I don't think my reading was insufficiently parsimonious.
