Using photons to manage data

Managing light to carry computer data, such as text, audio and video, is possible today with laser light beams that are guided along a fiber-optic cable. These waves consist of countless billions of photons, which carry information down the fiber across continents. A research team wants to refine the optical transmission of information by using a single photon, the fundamental building block of light that can allow unprecedented applications in optical information transfer.
