Researchers’ quantum hacking machine may help protect against quantum computing hacks

There seems to be no form of computing which is safe from hacking, but some, such as the Chinese, have pinned their hopes on quantum computing having uncrackable communications. Yet University of Ottawa researchers have managed to build “the first high-dimensional quantum cloning machine capable of performing quantum hacking to intercept a secure quantum message.”

Last year, China launched the world’s first known quantum communications satellite; the Chinese believed its Quantum Experiments at Space Scale (QUESS) satellite was a step toward “creating an unhackable communications system.” While it may seem like the Canadian researchers have poked holes in the dream of secure quantum communications, the opposite may actually be true.
