Information science: Quantum errors corrected
Andrew Steane1
Abstract
The phrase 'quantum error correction' might sound like a technical fix to a device that ought to be working better. But it is in fact a fascinating piece of fundamental physics with powerful implications.
Quantum error correction is a central concept of quantum information science and is almost the only thing a quantum computer would need to do if it is to work properly. It gives me great pleasure to say that it has now been implemented, in its most simple form, in a laboratory experiment reported by Chiaverini et al.1 on page 602 of this issue.
