Demonstration of Communication using Neutrinos (2012)
- tanto 9y agoWhat if the whole universe is full of life using Neutrino's for communiction and we just don't get it.
- hololight 9y agoThat was my first thought as well
- ianai 9y agoYou have to wonder how they scale it.
- kowdermeister 9y agoI'd recommend Stanislav Lem's His master's voice :)
- tyingq 9y ago"0.1 bits/sec with a bit error rate of 1% over a distance of 1.035 km, including 240 m of earth." I'm not sure that's much better than ULF, with similar issues on the size/cost of the transmitter. They do mention interstellar communication though.
- aomix 9y agoFrom discussions about this it seems like the consensus is that the nature of neutrinos would kill any attempt to make this method of communication scale. But boy it would cool to have straight line communication between any two points on earth no infrastructure required.
- mrfusion 9y agoWhat breakthroughs would be required to make this feasible for something the size of a flip phone?
- m1el 9y agoNot doable. A neutrino detector, including radiation shielding, cannot be the size of a flip phone.
- mrfusion 9y agoI’m thinking we’d need new physics discoveries. Maybe elements from the island of stability might help. Or something with superconductors. You never know.
- adrianN 9y agoIf new physics are allowed then it's simple. We just need a Neutrino detector that fits in a phone and doesn't need too much electricity.
- kobeya 9y agoThat would require a phone made out of something other than matter.
- pvg 9y agoGiven that these things are neutral and effortlessly fly out of collapsing supernova cores, heavier elements and superconductors are not very likely to help.
- netheril96 9y agoBy our current understanding, superconductors only exist under extreme cold, a condition never occurring naturally in stars and supernovas. So the fact that neutrinos fly out effortlessly does not preclude the possibility of a superconducting trap of neutrinos.
- chris_va 9y agoOne bit is sufficient if you are just trying to arbitrage markets. For a couple billion, an NYC to Tokyo neutrino shortcut wouldn't be a bad investment.
- thisisdave 9y agoAny individual bit could be noise, so it might take 2-3 bits to transmit something unambiguous (via an error-correcting code or similar). If so, I think the speed advantage disappears.
- chris_va 9y agoDetecting one pulse above background noise is not terrible, according to the paper. However, the way the paper sets up their communications channel is kind of silly, since they are pulse rate limited. If you wanted to transmit a lot of information with one pulse, you'd use time domain slicing and synchronized atomic clocks. Regardless, you don't need particularly high signal fidelity in order to arbitrage the market, just better than 50/50. The ~25ms they can cut off of the transmission latency is an eternity in market time.
- frumiousirc 9y agoThere is latency involved in both production and detection to contend with. NYC to Tokyo would require an unprecedented beamline angled deep down into the earth as well as a much more powerful proton driver to produce enough neutrinos to compensate for the 1/r^2 loss of flux. And, then there is the neutrino oscillation resonance due to the high matter density as the neutrinos pass near the Earth's core just to mix things up. The price tag for DUNE is a couple billion USD for a relatively "short" baseline of 1300 km and 40kton far detector. All that said, if some fat cat trader wants to fund it, I'll help build it.
