For decades, quantum computing has been the preserve of research labs. But now IBM has made its working prototype quantum computer accessible via the internet—and literally anyone can use it.
When Canadian Prime Minister Justin Trudeau schooled a journalist on the basics of quantum computing yesterday, I was initially as charmed and delighted as everyone else. But then a niggling sense of dismay set in. Why should this be such a singular newsworthy event? How come so few of us can do what Trudeau did, when…
Google’s AlphaGo computer may have bested a human in four out of five matches last month, but human beings still excel when it comes to intuitive leaps in problem solving. That’s the conclusion of a new paper in Nature by Danish scientists. Blending the two approaches yields the best of both worlds—a marriage of man…
Scientists have theorized for decades that an additional state of matter exists, but despite tantalizing hints to its presence, details about this mystery state have remained elusive—until now.
Quantum computers could immeasurably speed up the rate at which calculations run—but so far, their promise has yet to be realized. Now, a team of researchers has built a versatile quantum chip that it reckons could be pieced together to create a powerful computational device.
Programming a quantum computer is not straightforward. But playing computer games is–and this one will help academics gather information to help them write code for quantum computers in the future.
The NSA is worried about quantum computers. It warns that it “must act now” to ensure that encryption systems can’t be broken wide open by the new super-fast hardware.
A team of researchers from Google’s artificial intelligence labs has published results which it claims demonstrate that its controversial D-Wave quantum computer really works.
Quantum computing is a devilishly complex pursuit and one of the main problems is that it demands exotic materials to create its equally exotic circuitry. Now a team of researchers has managed to create the world’s first quantum logic gate in faithful old silicon.
Quantum computing could make complex calculations trivial in the future, but right now it's fraught with problems. Consider one of them solved, though, in the shape of a new quantum error correction technique.
You'd think quantum computers exist in heavily-guarded labs, with many men in white suits manning control stations filled with unfathomable screens and charts. Actually, they exist in a small cupboard in England's West Country.
Cooling modern-day computers is hard work: fans, heat sinks and even pumped liquid struggle to keep the temperatures of our hardware down. But how might we cool tomorrow's computers—those powered using the strange and exotic power of quantum physics?
The D-Wave 2 is a much-hyped quantum computer, but, as scientists now report, it's not actually any faster than a regular old PC. Wait, didn't we say it was 3,600 times faster just a few months ago? Yes, and both are right. Whether one computer is faster than another is actually a mighty complicated question.
A team of Dutch scientists just announced a new method of quantum teleportation that uses entanglement as a form of communication. They can successfully teleport data over a distance of ten feet. But, more importantly, they can also do so with 100 percent reliability.
Quantum computing is being hailed as the future of data processing, with promises of performing calculations thousands of times faster than modern supercomputers while consuming magnitudes less electricity. And in the span of just two years the only commercially available quantum computer, the D-Wave One, has already…
You will not be surprised to learn that the NSA is spending nearly $80 million trying to build "a cryptologically useful quantum computer." The Washington Post just published details of the program, codenamed "Penetrating Hard Targets," based on documents supplied by Edward Snowden.
Quantum computing will change our world. But currently, it's just about impossible. Qubits, the bits that power quantum computing, require crazy-cold temps to create, and they only survive about 3 minutes at room temp. Now, a research team has made room-temp qubits last for 39 minutes. That's monumental.
