Protecting quantum computing networks against hacking threats

As we saw during the 2016 US election, protecting traditional computer systems, which use zeros and ones, from hackers is not a perfect science. Now consider the complex world of quantum computing, where bits of information ...

Researchers break data transfer efficiency record

Researchers at the Department of Energy's Oak Ridge National Laboratory have set a new record in the transfer of information via superdense coding, a process by which the properties of particles like photons, protons and ...

Artificial atoms shed light on the future of security

From credit card numbers to bank account information, we transmit sensitive digital information over the internet every day. Since the 1990s, though, researchers have known that quantum computers threaten to disrupt the security ...

Quantum computing a step closer to reality

Physicists at the Australian National University (ANU) have brought quantum computing a step closer to reality by stopping light in a new experiment.

Graphene could revolutionize the Internet of Things

PFL researchers have produced a tunable, graphene-based device that could significantly increase the speed and efficiency of wireless communication systems. Their system works at very high frequencies, delivering unprecedented ...

Quantum fingerprinting surpasses classical limit

(Phys.org)—As the saying goes, no two fingerprints are alike, and the same is true for quantum fingerprints. Just as a human fingerprint is only a fraction of the size of a person, yet can be used to distinguish between ...
