Quantum sells so much product that its earnings might shrink

Quantum says it will make lower revenues than expected this quarter because it sold too many products and its supply chain couldn't keep up. How does that work? The data centre equipment firm thought its revenues for its second fiscal 2016 quarter, which finished on September 30, were going to be between $120m and $130m. Now …

The Quantum of solace: Well, at least the scale-out storage revenues were up

Quantum unsurprisingly saw declining revenues in its third quarter, hit by general storage market weakness and tape pricing falls which offset scale-out storage revenue increases. Revenues shrank 10 per cent annually to $128m in its fiscal 2016 third quarter ended Dec 31, 2015. They rose 9.4 per cent on the sequential compare …

D-Wave: 'Whether or not it's quantum, it's faster'

D-Wave is getting ready to drop a new benchmark on Arxiv, which the company says demonstrates its latest 1000-qubit processor outperforming classical machines. And it's bound to provoke the “other side” of the “is it quantum and is it faster?” debate, because the latest paper – the company has posted it here – describes “a …

Quantum's StorNext isn't storing up revenues fast enough

Quantum swung into loss-making territory with its latest quarterly results as reduced revenues couldn't cover existing costs. The StorNext ejector seat, as tape revenues crash and burn, maybe didn't operate fast enough.
