Entanglement unties a tough quantum computing problem


Hey! Look!

Some new ideas about the practical use of quantum entangled states:

“Error correction coding is a fundamental process that underlies all of information science, but the task of adapting classical codes to quantum computing has long bumped up against what seemed to be a fundamental limitation.

But a new approach by three theorists working at the USC Viterbi School of Engineering dramatically changes the rules of the game. Adding entangled photons as part of the message stream, they report in Science, opens the door to use of the entire error coding playbook. “

(If you need a quick refresh on what Quantum Computing is all about, this is a good place to find it. Here’s a more lay-person friendly treatment too.)
