Google: let's build our OWN quantum computer

Is Google gently backing away from D-Wave? That's one possible interpretation from this blog post, in which Mountain View tells the world it's going to add a quantum computer flavour to the Chocolate Factory. Google's Quantum Artificial Intelligence team is to partner with the University of California Santa Barbara “to design …
A quantum-diamond experimental chip at TU Vienna

Another step forward for diamond-based quantum computers

Building simple quantum gates is common, but creating something that could be built on transistor-like scale is a huge challenge. Now, boffins from the Technical University of Vienna, Japan's National Institute of Informatics, and NTT's Basic Research Labs are offering an architecture they reckon can be scaled up. What the …

If we don't do better, we'll hand over BOARD CONTROL - Quantum

Quantum’s directors appear to have agreed to hand over board control to activist investor Starboard Value if “certain ... objectives” are not met in its fiscal 2015 year. Starboard currently has three directors on the nine-person Quantum board and will get a fourth at Quantum’s 2014 meeting of stockholders, when its nominee Dale …

Quantum key security steps outside the box

US researchers have come a step closer to turning quantum key distribution (QKD) into a “black box” that can be made provably secure regardless of whose boxes sit at each end of a link. In creating a quantum crypto implementation, researchers rely on models of the systems they've created as proofs of their security. That means …
This geometric figure illustrates the concept of magic states and their relation to contextuality. The triangular region contains quantum states that are not magic and do not exhibit contextuality. States outside the triangle do exhibit contextuality and may be useful as a resource in the magic-state model of quantum computing.

Boffins lay out 'practical requirements' of 'realistic' QUANTUM COMPUTER

Canadian boffins have brought quantum computers a step closer to reality, by identifying one feature that will be key to finally building one – "contextuality". Our computers use the binary system of 1 and 0s. Quantum computers use qubits (quantum bits), which can exist in "superposition", meaning that they're simultaneously 0 …

D-Wave to bust 1,000-qubit barrier with new quantum compute device

D-Wave is planning a big expansion into quantum computing hardware and their software, helped in part by $30m in extra funding from venture capitalists. Vern Brownell, CEO of D-Wave, told The Register that his firm will use the bulk of the cash injection to expand out its software side to make it easier for customers to use the …

Quantum comms can be made even more secure

Quantum mechanics can be used to create the “perfect” digital signature, but in practice, it's held back by the technical impossibility of retaining quantum states for more than a few seconds. Now, a group of researchers from the UK, Croatia and Greece is proposing a scheme they say would make quantum digital signatures (QDS) …

Boffins: How to generate crypto-keys using a smartphone – and quantum physics

Your smartphone can be used to generate cryptographic keys from truly random numbers "of a quantum origin", according to bods at the University of Geneva. The Swiss research claims, quite simply, that illuminating the camera of a device like the Nokia N9 can cause quantum effects, which ultimately can be used to generate strong …

Don't get too excited, the world's not about to get Star Trek-style transporters. However, if a quantum communications theory formulated by three Tohoku University boffins can stand the test of experiment, they could break the distance limitations that currently constrain quantum communications. At this point, the exercise gets …

Boffins spot weirder quantum capers as neutrons take the high road, spin takes the low

Imagine this: when Australian cricketer Shane Warne bowled “the ball of the century”, a delivery that drifted one way, then hit the pitch and spun the other, the reason batter Mike Gatting was bamboozled was because the spin took a different path from the ball. That's the phenomenon boffins claim they've observed in experiments …
