Quantum Discord for Quantum Advantage

Quantum mechanics seems to be dominated by the fragile phenomena of superposition and entanglement that require special laboratory conditions to operate. This makes it very difficult for the advantages of quantum computing to come to personal computers, but new research from the National University of Singapore, Australian National University, University of Queensland, and University of Oxford might help change that.

Quantum discord is another phenomenon of quantum mechanics which is much more robust than entanglement and can carry information, as the researchers have shown. Quantum discord is the information shared between signals, like the music in an AM/FM simulcast. Even if the signals are distorted by noise, it is still possible to extract the music with the proper tools. Entanglement, on the other hand, would be the AM and FM transmissions carrying the music perfectly, but if there is any noise, the signal is lost.
