Quantum traffic jam of atoms could unlock origin of dark energy, physicists claim

It may be possible to crack the mystery of why the universe is expanding at an accelerated rate, if gravity can be measured through a “quantum traffic jam” of ultracold atoms. A paper published in Physical Review Letters [paywalled] proposes a hypothetical experiment that could provide scientists with a new way of measuring …

Quantum heaves sigh of relief as red ink washes away

Made it! Quantum is back in profit after five loss-making quarters. It made $3.8m profit on revenues of $134.7m in its second fiscal 2017 quarter; they were $117m a year ago, with a net loss of $11.2m, and $116.3m in the previous quarter, which saw a $3.8m loss. Finally all that hard work in building up StorNext revenues …

How do you make a qubit 10 times as stable? Dress it up for work

Dressing qubits in an electromagnetic field can make them 10 times more stable and able to perform more calculations over time in future quantum computers, according to new research in Nature Nanotechnology. Qubits - or quantum bits - hold information in quantum computers just like bits do in conventional computers. Instead of …

SHA3-256 is quantum-proof, should last BEELLIONS of years, say boffins

While it's reasonable to assume that a world with real quantum computers will ruin traditional asymmetric encryption, perhaps surprisingly hash functions might survive. That's the conclusion of a group of boffins led by Matthew Amy of Canada's University of Waterloo, in a paper at the International Association of Cryptologic …

Something strange stirs in the storage backwater swamps, long ribbons of rust that never forget

At one end of the storage spectrum is fast and flashy SSD storage and at the other – still – is tape; streaming ribbons of rust that are cheaper and more reliable than disk, and still selling for on-premises and off-site archive data storage. Long-time tape library and drive supplier Quantum has brushed up its library offering …

HyperGrid's CMO loss is Nexsan's CMO gain

Victoria Grey has left her CMO position at hyper-converged vendor HyperGrid to take on a chief marketing officer role at traditional storage array vendor Nexsan. Nexsan is Imation’s storage array product set with added file sync and share capabilities. Grey’s Twitter profile declares she is “Acting CMO for Nexsan.” She was …

Tiery-eyed NetApp previews on-prem storage and cloud tie-up

NetApp has previewed a FabricPool technology which combines on-premises and AWS cloud storage into a single repository. This is part of NetApp's overall Data fabric strategy of converging and integrating on-premises storage with the public cloud. Joe Caradonna, senior technical director at NetApp, presented Fabric Pool at …

Quantum comms succeed over metro-scale fibre networks

Two groups both reported successfully teleporting state information across metro-scale fibre networks. A Chinese team is claiming a teleportation over a 30 km fibre in Haifei (the entanglement travelled nearly 16 km), while the University of Calgary used that city's fibre network to carry entanglement 6.2 km (preprint here). …

The Rector reckoning – DataDirect loses CMO

HPC and enterprise high-performance storage company DataDirect Networks has lost Molly Rector, its chief marketing officer, who has moved to take up a VP marketing role at Quantum. Robert Triendl has been promoted to DataDirect's SVP global sales, marketing and field services from a position as SVP for HPC strategy. He tells …

Quantum leap: A good quarter for disk backup gear, and yeah tape's OK

Quantum’s first fiscal 2017 quarter – the three months to June 30, 2016 – showed revenue growth as the tape market stabilized and big deals came good. Revenues of $116.3m were five per cent higher than last year’s $110.9m. There was a net loss of $3.8m, better than the $10.8m loss recorded a year ago and the unfortunate $52.4m …

Quantum is shutting down sync'n'share biz Symform in July

Storage firm Quantum bought the Symform cloud consumer/small business file sync and share business in August 2014 – and is going to close it down on July 31. It has gone from acquisition to closure in 23 months. Why? According to a Quantum FAQ: "Quantum is discontinuing the Symform service due to its strategic business focus …

It's not us, it's you: Boffins ditch supercomputers in lust for new materials

Physicists from the National Institute of Standards and Technology have created a quantum simulator designed to model complex quantum mechanics phenomena that even the fastest supercomputer could not compute. The researchers created the simulator by trapping up to 219 beryllium ions inside a Penning trap in a bid to study …

The Quantum of Solace: You've still got tape. Don't forget that

Quantum’s latest results show that scale-out storage is still not growing fast enough to outweigh declining tape storage revenues – and Quantum is still a shrinking business. Let’s do the annual numbers to show the big picture first. Revenues for the full fiscal 2016 year, ended 31 March, were $475.9m, down 14 per cent year- …

Sail on SpectraLogic's BlackPearl, right up into the cloudy glory

SpectraLogic has added replication and a cloud gateway to its BlackPearl disk and tape storage combo. Where large-scale content providers need to store their relatively unstructured content (videos, etc) on a tiered disk and tape system for fast front-end disk access and low-cost long-term back-end tape, then BlackPearl …

Quantum of solace: Mega cloud signing to end years of hurt?

Quantum says it has won a major cloud storage deal that could help reverse years of falling revenues. It's also announced a new chief financial officer: Fuad Ahmad will take over from Linda Breard. Breard became Quantum's chief beancounter in January 2011, and resigned in January to pursue another opportunity. Ahmad gets an …

NIST set to shake up temperature with quantum thermometer

A moment with Google will reveal all kinds of cranks offering “free” energy from quantum “zero-point” phenomena, but it's a real thing with real effects. At the tiniest scales, quanta vibrate, even at their lowest energy. If all motion ceased, an observer would be able to breach uncertainty theory. Now, National Institute for …

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 …

Google says its quantum computer is 100 million times faster than PC

Two years ago Google and NASA bought a D-Wave 2X quantum computing system and the Chocolate Factory has now pronounced itself very pleased with the results. "We found that for problem instances involving nearly 1000 binary variables, quantum annealing significantly outperforms its classical counterpart, simulated annealing. It …
