Los Alamos Has Ultra-Secure 'Quantum Internet'

Researchers have been using it for more than 2 years

(Newser) - The concept of a "quantum Internet" is like the holy grail of online security—any such system would guarantee that all communication is safe. Now it appears that researchers at Los Alamos have made real progress: They've been using an uber-secure system of their own design for about... More »

Photons 'Entangle' Way Faster Than Light Speed

Physicists try to measure 'quantum teleportation'

(Newser) - Quantum action occurs very, very quickly—at least 10,000 times the speed of light. That's the finding of a team of Chinese physicists who tried to measure the interaction between entangled photons, LiveScience reports. In case you don't know: "Connected" photons can be separated but still... More »

New 'Quantum Teleportation' Record Wows Scientists

Photons send quantum information across 89 miles

(Newser) - Quantum teleportation won't beam you up to the Starship Enterprise—at least not yet. But scientists are able to tweak "entangled" photons at greater distances than ever before, Scientific American reports. In case you haven't been freaked out yet: Scientists can separate two photons by dozens of... More »

Hawking Out $100 Over Higgs Discovery

He bet Michigan prof that particle would never be found

(Newser) - The apparent discovery of the Higgs boson particle has come at a cost to Stephen Hawking: The world-renowned physicist has lost a $100 bet with Gordon Kane of Michigan University that it wouldn't be found. "It seems I have just lost $100," Hawking tells the BBC . "... More »

God Not Necessary for Big Bang: Scientists

But that doesn't mean there is no God

(Newser) - The Big Bang could have brought the universe into existence whether or not God exists, researchers said at the recent SETICon 2 conference. "The Big Bang could've occurred as a result of just the laws of physics being there," said one astrophysicist. "With the laws of... More »

Scientists: Time Travel Impossible

Researchers prove nothing can violate the 'traffic laws' of the universe

(Newser) - Wait, so Bill And Ted's Bogus Journey is suddenly implausible? A group of Hong Kong University of Science and Technology physicists say they've proven that time travel is physically impossible, reports Discovery News . They demonstrated that a single photon obeys Einstein's theory that nothing can travel faster... More »

Antimatter Captured for First Time

CERN: Experiment is 'science fiction become science fact'

(Newser) - Atoms of antimatter are instantly destroyed when they come into contact with matter, so capturing them by the dozen was no easy task, say scientists at CERN. A team of scientists at the European institute managed to capture 38 of the atoms for a fraction of a second, each in... More »

Why Physicists Clean Up at Poker

To start, they understand numbers

(Newser) - What's the not-so-simple secret of playing poker? Quantum physics, finds NPR . It turns out that several top players are physicists—and that's no fluke. Physicists understand probability, statistics, and modeling. "I mean—when you think about it—they build models of the world," says Jennifer Ouellette, author of... More »
