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 »
