Donuts, math, and superdense teleportation of quantum information

Quantum teleportation has been achieved by a number of research teams around the globe since it was first theorized in 1993, but current experimental methods require extensive resources and/or only work successfully a fraction of the time. Now, by taking advantage of the mathematical properties intrinsic to the shape of a donut — or torus, in mathematical terminology — a physicists have made great strides by realizing ‘superdense teleportation.’
