‘Game-changing’ quantum breakthrough paves way for safer online communication

The technique applies a principle called entanglement which Albert Einstein described as “spooky action at a distance”

The world is one step closer to having a totally secure internet and an answer to the growing threat of cyber-attacks, according to scientists.

A prototype, designed by a team at the University of Bristol in England, could transform the security of online communication for millions of people across the globe.
