Cybersecurity Is About To Get Quantum Upgrade
Researchers at the University of Sydney just made a major breakthrough in cyber security. They managed to get single photons to behave as carriers of quantum information in security systems. Their work brings us one giant step closer to developing password exchange mechanisms that can only be broken by breaking the laws of physics.
“Quantum communication and computing are the next generation technologies poised to change the world,” said Dr Chunle Xiong from the School of Physics at the university.
Generating photons is a tricky business, but is vital to reliable quantum communications. Photons are generated simultaneously in entangled pairs, each in one of two photon streams. Detecting photons in one stream reveals information about the timing of photons in the other. This allows for extremely precise management of photon events.
