- ncmncm 7y agoYes, but that typically takes government cooperation, and you still don't get better latency -- even if you have neutrinos.
- moonbug 7y agowhat?
- ncmncm 7y agoCertain labs were sending neutrinos right through the earth, gaining a measurable reduction in transit time vs great-circle overland signal propagation. (At first they thought they were gaining even more, by superluminal transit, but that turned out to illusory.) They did not put any data in the neutrino channel, to my knowledge, but in principle they could have. You might think you would need quite a deep chord to beat microwave propagation over the surface, because the dielectric coefficient of rock reduces the speed of light there. But that wouldn't affect neutrinos, which definitely go much faster through any kind of rock than light ever goes down a fiber. True fact.
- exikyut 7y agoIf there's any possible way you could share more about this... I am very very interested to learn more.
- sgt101 7y agoBear in mind that you have to put the signal in and get it out of the channel as well as transmit it. I highly doubt that neutrino signaling kit is as optimized for doing this as photonics.
- ncmncm 7y agoTo be clear, there is absolutely no practical means of high-speed data communication using neutrinos. That is not to say there will never be any.
- exikyut 7y agoAh, I see. So the labs you refer to were trying to make this work? I'm curious what sort of performance level they achieved, even if eg just multiples of single or tens of bytes/sec. Thanks for the info.
- ncmncm 7y agoNo, they were just producing neutrinos, detecting them, and measuring transit time. But you have to turn the neutrino flux off and on, or at least vary the intensity, to have something to measure. You might have been able to get tens of bits per second with their apparatus. Or per hour. Look up "superluminal neutrinos" and work your way past the scandal to the actual experiment..
- sgt101 7y agoIt doesn't, it takes buying access to a link. Latency isn't the problem here - it's throughput.
- ncmncm 7y agoOh, how nice it would be to live in such a simple world. Latency turns out to have a very great deal to do with how hard it is to get the nominal throughput you pay for.
