RT @newsycombinator: IBM shows off quantum computing advances, says practical qubit computers close via @LetterOwl:

Quantum scientists at IBM Research have announced major advances in quantum computing that could place real, practical quantum computers in businesses and homes within the next 10 years.

The main breakthrough revolves around the long-term integrity of qubits. To perform quantum computing, you need to be able to reliably store and interrogate qubits — but qubits are incredibly flighty creatures that readily change their state through decoherence. IBM has created a high-coherence 3D qu...
