Journal tqft's Journal: Quantum Randon Numbers 10

Journal by tqft on Friday April 13, 2012 @04:30AM

What the world needs is more truly random sources of numbers. Here are some more:

" We do this by splitting a beam of light into two beams and then measuring the power in each beam. Because light is quantised, the light intensity in each beam fluctuates about the mean. Those fluctuations, due ultimately to the quantum vacuum, can be converted into a source of random numbers. Every number is randomly generated in real time and cannot be predicted beforehand. So if you need some really random numbers, use the link below!"

  Yeah. I put it in my twitter stream, never know if anyone saw it.
  Not sure there is something you can call across the network which would make it mega nifty.
  I did actually put this through as a submission, never know.

    If this doesn't get on the front page, slashdot has truly jumped the shark. This is as nerdy as it gets....

    Are you sure you submitted it correctly? (You have a typo in the headline... Random). I didn't find it in the firehose, as I wanted to upvote it.

      In the firehose now

      I suspect submitting je's as stories no longer works.

        Voted up... You're already at "yellow", whatever that means.

        You're in the mysterious future now :-) In a bit more than an hour from submission to front page....

This is very cool. I nodded the submission in the FireHose.
Another interesting approach Ito true randomness: The guys ate SparkFun [sparkfun.com] used a Geiger counter to decide when to give out prizes on their last freeday. In that implementation it was only giving random true/false, but that could be extended to produce numbers as well.

  Thanks
  I think submission via journal maybe broken
