Quantum communication schemes using light normally rely on the two types of photon polarization to encode information a bit at a time. But if researchers could efficiently measure a photon's orbital angular momentum, which can take an infinite number of different values, they could conceivably pack much more information into a light beam. A team of physicists has recently reported a way of sorting individual photons according to their orbital angular momentum, which could allow them to make use of all that extra data.
