Scientists achieve critical steps to building first practical quantum computer

Commentary by Stephen Downes

This is pretty interesting. To create a stable quantum computer, you have to simultaneously detect for two types of error, bit-flip and phase-flip errors. This article describes a quantum computer that can detect both simultaneously. As the article notes, "Quantum information is very fragile because all existing qubit technologies lose their information when interacting with matter and electromagnetic radiation," so error detection is especially important. Quantum computers, when developed, will represent an increase in speed in orders of magnitude, making currently intractable problems (like decryption, modelling and optimization).  More: magic-state error detection, error-correcting quantum computer, using parity checks in error detection, original journal article.
