“Teleporting” Images Across a Network Securely Using Only Light
University of the Witwatersrand, Johannesburg

Nature Communications today published research by an international team from Wits and ICFO- The Institute of Photonic Sciences, which demonstrates the teleportation-like transport of “patterns” of light – this is the first approach that can transport images across a network without physically sending the image, and a crucial step towards realising a quantum network for high-dimensional entangled states.

New calculations predicting the spatial distributions of the charges, momentum, and other properties of the quarks within protons found that the up quarks are more symmetrically distributed and spread over a smaller distance within the proton than the down quark. The results imply that these two types of quarks contribute differently to a proton’s properties.
