Twisted lights in the sky

Twisted light.  Polarized in a new and different way?  Or a way I just never heard of?  Really?  Or maybe it’s just a new application of circular polarization?  Not sure.  But anyway, 2.5 terabits of information a second would be nice to have for communicating in space, between probes and the homeworld.  Between homeworlds in the cosmic civilization-scale jetlag.

  1. They’re playing with the helicity of the transmitted waves as the dominant carrier, instead of the polarization. I’m unsure how robust these signals are (they only managed to transmit about a meter) and you need to make sure you’re focused point-to-point, but it’s still cool and the pictures are pretty.
