Instant, secure ‘teleportation’ of data in the works

Sending information instantly between two computer chips using quantum teleportation has been accomplished reliably for the first time, according to scientists from the University of Bristol, in collaboration with the Technical University of Denmark (DTU). Data was exchanged without any electrical or physical connection – a transmission method that may influence the next generation of ultra-secure data networks.

Teleportation involves the moving of information instantaneously and securely. In the “Star Trek” series, fictional people move immediately from one place to another via teleportation. In the University of Bristol experiment, data is passed instantly via a single quantum state across two chips using light particles, or photons. Importantly, each of the two chips knows the characteristics of the other, because they’re entangled through quantum physics, meaning they therefore share a single physics-based state.
