FUTURE OF CONNECTIVITY
Quantum communication is a giant leap for humanity
The Chinese have demonstrated a quantum link across 1,200km in space
The Structured Light Laboratory at the University of the Witwatersrand is pushing the limits of fast, secure communication with new research into quantum technologies for communication systems. Under the leadership of Prof Andrew Forbes, the laboratory has published its third major paper in 2017 on quantum advances, describing the building blocks of a quantum communication system with high dimensional states. This paper, published in Nature’s Scientific Reports, follows one on demonstrating quantum teleportation (published in Nature Communications) and a means to correct quantum errors in real time (in Nature Physics). In combination, these advances provide a platform for a new technology for secure and fast data transmission. "We are currently building a prototype device with the support of the Technology Innovation Agency, which will allow a secure quantum communication link to be established across a long distance between two parties — say two banks or between military bases," sa...
