How To Encode 2.05 Bits Per Photon, By Using Twisted Light

Thorfinn.au writes Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using "twisted light." [Abstract here.]This remarkable achievement is possible because the researchers used the orbital angular momentum of the photons to encode information, rather than the more commonly used polarization of light. The new approach doubles the 1 bit per photon that is possible with current systems that rely on light polarization and could help increase the efficiency of quantum cryptography systems.

Anybody else read this and think, "Oh come on ... the physicists are just getting silly and making up shit now."

I'm still waiting for somebody to synthesize this whole field and make it halfway possible to visualize.
