Intel's 17-qubit quantum chip

Look! Over there! Intel's cooked a 17-qubit chip quantum package

Intel reckons it's stolen a base in the race to build quantum chippery, by shipping a cryogenically-cooled 17-qubit chip to Netherlands-based QuTech. QuTech is Chipzilla's quantum research partner – QuZilla, so to speak. Regular readers of spooky-action-stories will know a qubit is a fragile creature, losing data if there's …

IBM has cloud access to quantum computer 400 times smaller than D-Wave system

IBM says it will build commercially available quantum computing systems accessed through its cloud platform, but D-Wave has a claimed quantum computer 400 times bigger. Quantum computing has the promise of outperforming today's computers to an extraordinary degree at certain tasks such as factoring very large numbers. It uses …

Intel-backed boffins demo long-lived silicon qubit

Bit by bit, the world gets closer to creating the quantum equivalent of a storage gate – a silicon-based qubit that can last long enough for general-purpose computing. If you want to use the superposition – the quantum property in which a gate can exist as 0 and 1 at the same time – for computation, it needs a usable “ …

Google tests its own quantum computer – both qubits of it

A couple of years ago, a quantum physicist suggested to Vulture South that one of the best uses for quantum computers might be to model reality. Now, Google reckons its boffins have done just that. Science wants to model quantum systems because they lie at the heart of reality. For example, chemistry – where Google has chosen …

Physicists build simulator, hope to stand up beautiful Standard Model

Physicists have built a quantum simulator to study the Standard Model of particle physics – a theory concerning the electromagnetic, weak, and strong nuclear interactions, as well as classifying all the subatomic particles known. The simulator includes lasers and four calcium ions, according to new research published in Nature [ …

Boffins slap quantum dots on diamonds to create mutant nanomaterials

Researchers have found a new way to speed up the process of doping nanomaterials by adding quantum dots to tiny diamonds, which could advance electronics and quantum computing in the future, according to a paper published in Nature Communications. Nanomaterials have properties that are useful in electronics. Electrons travel …

Australian boffins say Quantum Pentiums are on the horizon

Australian boffins have overcome one of quantum computing's big problems by building a gate comprised of two qubits in silicon, using techniques very similar to those used to manufacture whatever device you're using to read this story. Building a quantum logic gate in silicon is a big deal because hitherto it's only been …

D-Wave promises chip that could SEARCH THE WHOLE UNIVERSE

The 1,000-qubit chip promised by D-Wave last year has landed. The 1,000-plus-qubit device was originally planned for the end of 2014. The doubling of qubits over its previous processor, the company says, gives it a 21000 search space – not only dwarfing the previous 2512 search space, but containing “far more possibilities …

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 …

Microsoft in hunt for the practical qubit

Redmond says it has joined the search for a practical qubit, in an effort to kick along the development of quantum computers. Head of research at Microsoft Peter Lee has told the MIT Technology Review digital summit that Redmond will be supporting research in other labs with funding, as well as doing its own work at its …

QUANTUM COMPUTER in WORLD RECORD qubit stunner

Researchers have managed to store data in a qubit – a quantum computer's binary bit – and maintain it in a superposition state, where ones and zeros exist simultaneously, for 39 minutes, beating the previous record of just a few seconds. qubit Hot stuff! What an artist reckons a qubit looks like "This opens up the …

Spin doctors brazenly fiddle with tiny bits in front of the neighbours

The University of New South Wales, working with Sandia National Laboratories in New Mexico, is celebrating what it hopes will be another step towards large-scale quantum computing: a technique that can address single electron qubits separated by mere nanometres. Quantum bits - qubits - are the quantum-physics counterpart to …

Boffins spin a solid state qubit in a nucleus

A group of researchers from the University of New South Wales has produced a functioning solid-state qubit with a read-out fidelity of 99.8 percent, taking the world another step along the path towards a functioning quantum computer. The team used the magnetic spin of the phosphorus nucleus as the basis for their experiment, …

Entangled matter the next big thing in qubits

Researchers at the Max Planck Institute are trumpeting as a breakthrough the successful teleportation of quantum information over 21 metres. To be fair, however, the record they're claiming to have set is for “matter-matter teleportation” – rather than merely carrying a quantum state such as polarisation between a pair of …

Boffins spin up working Qubit in silicon

The University of New South Wales' School of Electrical Engineering and Telecommunications has created what it says is the world's first working qubit based on a single atom. Detailed in a new Nature paper, A single-atom electron spin qubit in silicon, the qubit relies on the ability to impart “spin” to an electron bound to a …

Quantum computing IN OUR LIFETIME - IBM breakthrough

IBM boffins reckon their research has catapulted quantum computing forward a few decades, making it possible within our lifetime. The scientists say that they've come up with a way to extend the amount of time that qubits retain their quantum state, thereby reducing errors in computations. “In the past, people have said, …

Future quantum computers could be made of... silicon?

In a slightly retro move, a top Blighto-Dutch boffinry alliance has declared yet another method of creating a practical "qubit" - a building block of the postulated weird yet puissant quantum computers of the future. This time the tiny piece of unknowable information is contained, not in some exotic new ultra-substance, but …
