GCHQ boffins quantum-busted its OWN crypto primitive

While the application of quantum computers to cracking cryptography is still, for now, a futuristic scenario, crypto researchers are already taking that future seriously. It came as a surprise to Vulture South to find that in October of this year, researchers at GCHQ's information security arm the CESG abandoned work on a …

Simon's says quantum computing will work

One of the hard parts of quantum computing is turning laboratory qubits into a calculation of anything. Now, South African scientists claim they've tested a handful of qubits against a 20-year-old algorithm to demonstrate that yes, a quantum computer can run it “faster” than a classical machine. Regular readers of quantum- …

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 …

UK boffins: We'll have an EMBIGGENED QUANTUM COMPUTER working in 5 YEARS

Oxford boffins have vowed to have the largest quantum computer ever made up and running within five years and help Blighty regain its place at the top of the tech world. The government has announced the creation of four "Quantum Technology Hubs" which will collaborate to build a small device called the Q20:20. Sadly, this won't …

Quantum computing is so powerful it takes two years to understand what happened

In 2012 a group of Chinese quantum physicists pulled off an acclaimed success in quantum-based factoring, running an adiabatic quantum algorithm for the number 143, at the time believed to be the largest number ever factored in a quantum computation. It now seems that paper, here, could have overlooked something: in a new paper …

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 …

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 …

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.
