Photons Orbital Angular Momentum Measured For First Time

Interesting... a team from Scotland has managed to measure a photons orbital angular momentum, (see this paper.) which can be used to encode information. Seems kinda like an optical MUX has been written into the source code of the universe. Also has implications for quantum cryptography.
