You can now tinker around with IBM’s quantum computers – straight from your couch

Quantum computing is still in its infancy, but you can test drive it yourself thanks to IBM.

Quantum computers might soon render RSA encryption obsolete

Using only five atoms, a team of international researchers showed how to factor a prime, albeit a trivial one for demo purposes.

Quantum computers explained by the man behind the first such machine

D-Wave, a company that claims it’s the first to build a quantum computer, has been making headlines recently after Google and NASA proved that one of its machines can indeed perform quantum operations. Though not a universal quantum computer, the D-Wave machines suggest that this target might not be far off. This is subject that deserves a lot more interest, though, and if you don’t know anything about quantum computers (where to start, right?), I suggest you check out this great talk by the D-Wave founder and CTO, Geordie Rose. In a quarter hour or so, Rose speaks about how quantum computers work, in principle, and how we have to stretch our perception to fit parallel universes to be able to conceive them. He also makes three crazy predictions, which I won’t spoil. Enjoy!

Quantum version of computer code proven to work in silicon chip

University of New South Wales devised a two-qubit system inside a silicon chip and ran a computer code adapted to the quantum world. Their code passed the notoriously intransigent ‘Bell test’, making it the strongest evidence yet that quantum computers can be instructed to handle operations.

Two-qubit silicon quantum computer works for the very first time

Quantum computing is one of the future’s transitional technologies destined to transform human society, along with advanced materials like graphene and metallic glass or advances in space propulsion. Imagine what the transition from vacuum tubes to transistors did for computing, scale that a couple of folds and you might somewhat be close to what quantum computers are capable of. Operations that today’s supercomputers require days even weeks to crunch, would be completed immediately by leveraging the quantum weirdness that happens below the nano scale. All of this is theoretically possible – but in practice building a working quantum computer that doesn’t disintegrate information has proven to be an immense challenge. We’re still far from there, but advances reported by Australian researchers hint that quantum computers aren’t a pipe dream.

Intel invests $50 million in quantum computing

Today, Intel announced a 10 year collaboration with Delft University of Technology and TNO, the Dutch Organisation for Applied Research, to accelerate and enhance the advancements in quantum computing: the new type of computing which promises to revolutionize the world as we know it

Squeezing Schrödinger’s cat to measure sensitive quantum states

Researchers at ETH Zurich “squeezed” the quantum states of a calcium ion to make it easily distinguishable, i.e. they measured one of its physical quantities more precisely. All while working within the confinements of Heisenberg’s Principle of Uncertainty (as if they had a choice). The findings could prove useful for ultra-precise measurements which are particularly sensitive to unwanted external influences.

Rice grain-sized laser helps build the first quantum computer

Princeton researchers demonstrated a novel type of microwave laser – called a maser – so small that’s the size of a grain of rice. The laser is powered by individual electrons that tunnel through artificial atoms known as quantum dots.

The quest for the quality qubit: quantum computer based on trapped ions has error rate of only 0.07%

Who would’ve thought only a decade ago that quantum computers would become real in the upcoming future? Those of us without such hindsight need to rely on what’s been reported by scientists, and recently all kinds of developments lend us to think that a quantum computing future isn’t that far off. Take the latest qubit experimental set-up made at University

Milestone algorithm runs for the first time on a quantum computer

A 20-year-old algorithm that demonstrated the benefit of using quantum mechanics to solve certain problems has finally been run on a quantum computer – a sweet delicious treat, and a sign that serious progress is being made in the field of quantum computing. The Quantum world is weird A quantum computer is a computation system that makes direct use of

D-Wave claims it wants to release a 1,000 qubit quantum computer in 2014

A lot of hype has been going D-Wave’s way in the past decade or so. The company is considered by many the leading quantum computing company in the world, boasting clients such as Lockheed Martin or Google. Before munching up on the hype, though, it’s important to understand that to this day no one has been able to build a

Storing one bit per atom: more storage power and closer to quantum computers

There’s only so much you can cram into conventional magnetic storage devices. We’re already seeing these slowly, but surely lose ground in the face of solid-state drives, which offer more storage density and don’t have any moving parts (last longer, make no noise, etc.). What about even further ahead in the future? Well, it’s most likely that in the following

Understanding a unique type of magnetism

Using low-frequency laser pulses, a team of researchers has carried out the first measurements on a mineral called herbertsmithite. This (pretty awesome looking) mineral features a unique kind of magnetism. Insite it, magnetic elements constantly fluctuate, leading to an exotic magnetic state, unlike conventional magnetism in which all magnetic forces allign in the same direction and also unlike antiferromagnets, where

An insightful animation on quantum computing [VIDEO]

Theoretical Physicists John Preskill and Spiros Michalakis  sat down for a short talk in which they describe how quantum computing differs from the classical view (i.e. digital computers). They first go on about the fundamental, key aspect of the quantum world: the laws that describe and govern things at the tiniest level differ from those at the macroscale. The revealing

Direct measurement of Van der Waals force made for the first time

Scientists at the Laboratoire Charles Fabry (LCF) in Palaiseau and the University of Lille have for the very first time performed a direct measurement of a Van der Waals force – the weak intermolecular force that causes, in some cases when there isn’t a strong force present, to attract and “stick” to one another. The Van der Waals force is what
