US Had Fastest Supercomputer. Now We're Not in the Top 3

Once first, Titan is now the world's fourth fastest

(Newser) - America's fastest supercomputer is Titan, a beast that lives up to its name thanks to its ability to perform 17.6 quadrillion calculations per second. But its computing power is now only the fourth strongest in the world. As it did in 2016, the title goes to China's... More »

Go Ahead, Ask Justin Trudeau About Quantum Computing

Canadian PM takes joke question, answers like a boss

(Newser) - It was a joke of a question—"Morning, sir, I was going to ask you to explain quantum computing, but...."—but Canadian PM Justin Trudeau not only took the question, he knocked it out of the park on Friday, giving a concise, enthusiastic, and impromptu lesson on... More »

Computer Crunches Data —in Different Universes?

D-Wave says it's built a quantum machine, but skeptics aren't buying it

(Newser) - For many people, it's simple: Either you believe in D-Wave or you don't. The Canadian company claims to be building "quantum computers," which operate based on quantum mechanics and can theoretically perform 2-to-the-power-of-512 operations at the same time—more calculations than there are atoms in the...

NSA Working on Computer to Crack Almost Any Code

Washington Post says agency has $80M invested in futuristic quantum computing

(Newser) - The Washington Post is out with a doozy of a story for its latest Edward Snowden scoop. It says the NSA is trying to build a quantum computer that "could break nearly every kind of encryption used to protect banking, medical, business and government records around the world."... More »

Quantum Internet Gets Closer

New kind of Net would be automatically secure

(Newser) - A recent quantum computing breakthrough is a step towards creating a quantum Internet—which would be "automatically secure," a researcher told Technology Review. A Northwestern University professor has created a fundamental element of a quantum computer, a quantum logic gate, within an optical fiber, where previous gates used... More »

Quantum Computing Works in Experiment

Atomic-level computer could change world

(Newser) - In theory, a quantum supercomputer would be insanely powerful. By manipulating atoms, quantum bits—qubits, for short—would never be definite 1s or 0s. Instead, they would be both at once, in theory allowing a device using them to solve nigh-impossible problems. That theory is getting closer to reality, Ars... More »
