From the abstract: "The link achieved a decoded data rate of 0.1
bits/sec with a bit error rate of 1% over a distance of 1.035 km, including 240 m of earth." http://arxiv.org/pdf/1203.2847v1.pdf For practical communications, at longer distances, you probably lose beam intensity as a 1/R^2 function (the neutrino beam isn't precisely collimated), so 1,000 km away it will be 1 millionth as strong, or 0.0000001 baud, 1 bit per 115.74 days. At 2,000 km it would be less than 1 bit per year. Sure you want to do this? 8-) On Fri, Mar 23, 2012 at 2:44 PM, Simon Lyall <simon () darkmere gen nz> wrote:
You guys joke but here is n little article from last week on the current state of Neutrino communications: http://www.economist.com/node/21550242 "The neutrinos themselves are created by smashing bunches of protons into a target made of graphite. They are detected roughly 1km away by researchers [..] . By modulating the pulses of protons the group was able to send a message in binary that, when translated, read “neutrino”.
