Well, since we are talking books, help me out with something. My wife’s Starstruck series of novels involve some super-advanced aliens called the Grentl (the allusion to legend of Beowulf is deliberate). These aliens are not actually seen (at least in the six books so far) but in the later books the heroine does communicate with them. My wife sought a science fictiony explanation for instant communication over many light years distance. She wanted something that would be effectively instantaneous but of low bandwidth. As her informal “science advisor” for the books I struggled to provide an answer.
I suggested something I dubbed the “quantum telegraph” (a term I felt very descriptive for the concept). The theory was the Grentl developed a device somewhat similar to the one tested in your article. If one can detect changes in quantum states instantaneously, as the article suggests, then a binary on/off (or perhaps up/down) code seems to be possible. A series of “dots and dashes” in this sense could provide the instant communication desired.
Now here’s the thing. As plausible as this sounds to me, I intuitively feel it can’t actually work as I suggest without really pissing Einstein off. But I don’t know why. I feel I must be missing something fundamental but I can’t figure out what it is, even after reading your very informative article. So my question to you is, what am I missing here?
For the record, other than calling the device a “quantum telegraph” my wife went into none of this in her books. Further it ended up being rather super high bandwidth. As it turns out, low bandwidth slows down the storyline. She also has not yet used my brilliant idea for a “tachyon generator” which is like zero point energy on steroids. What can I say?
Thanks in advance should you choose to accept this question.
