The quantum hacking efforts could be used to study quantum communication systems or more generally to study how quantum information travels across quantum computer networks. “Our team has built the first high-dimensional quantum cloning machine capable of performing quantum hacking to intercept a secure quantum message,” said Ebrahim Karimi, a professor at the University of Ottawa in Canada. “Once we were able to analyse the results, we discovered some very important clues to help protect quantum computing networks against potential hacking threats,” said Karimi. “We were also able to show that cloning attacks introduce specific, observable noises in a secure quantum communication channel,” said Bouchard.
