“It’s amazing no-one had thought of it before,” said one of the scientists involved.
Prepare for some quantum madness.
No everyone is convinced this machine can actually perform quantum operations, though.
For the first time, a team of researchers claims it’s made a fully programmable and reconfigurable quantum computer module.
Quantum computing is still in its infancy, but you can test drive it yourself thanks to IBM.
Using only five atoms, a team of international researchers showed how to factor a prime, albeit a trivial one for demo purposes.
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!
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.
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.
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
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.
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.
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
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
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
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
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
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
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
If you did intermediate math in school, then you’ll most likely remember how to split numbers into prime factors; basically, any number can be written out by multiplying prime factors. Now, a group of researchers from UC Santa Barbara has designed and fabricated a quantum processor capable of factoring a composite number. Don’t get overexcited though, because the number is
