IARPA: Come, quantum computing boffins. We've got cash for you

Nay-sayers may nay-say, but America's Intelligence Advanced Research Projects Activity (IARPA) reckons research into quantum computing is advanced enough to warrant a five-year program to kick things along. It's kicked off what it the Logical Qubits (LogiQ) program here, and it's looking to fund work building current science …

Incomprehensible boffins bring quantum computers a step closer

The long-awaited arrival of quantum computers could be one step closer, as boffins from Oz have for the first time encoded quantum information in silicon. Unlike conventional computers, which store data on transistors and hard drives, quantum computers encode data in states of microscopic objects called qubits. The arrival of …

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. As its forewarning indicated, revenues in the quarter ending 30 June were down 13 per cent to $110.9m, from …

Quantum blames wobbly storage world for its own wobbly financials

They say that when the tide goes out you can see who's been swimming naked. It's going out for Barracuda, QLogic, and Seagate, and Quantum makes four as it bares lousy preliminary Q1 numbers.

Simon's says quantum computing will work

One of the hard parts of quantum computing is turning laboratory qubits into a calculation of anything.

Canadian boffins have brought quantum computers a step closer to reality, by identifying one feature that will be key to finally building one – "contextuality".
