In This Image, Two Photons Interact. Here's Why It's Groundbreaking.

Normally, photons want nothing to do with one another. Light waves just pass through each other like ghosts. But now, for the first time ever, scientists at the University of Vienna have coaxed a strong interaction between two single photons. It's an achievement that opens up radical new possibilities for a number of… » 11/04/14 12:30pm 11/04/14 12:30pm

Teleportation just got easier – but not for you, unfortunately

8

Thanks to two studies published in Nature last Thursday, the chance of successful teleportation has considerably increased. Which is a good thing, right? » 8/23/13 2:51pm 8/23/13 2:51pm

Scientists teleport information in an electronic circuit

We’re still a far way’s off from being able to beam people through space, but in a science first, physicists have successfully transported information across a solid state system similar to a computer chip. The breakthrough could lead to more powerful processors and highly sophisticated encryption schemes. » 8/15/13 11:30am 8/15/13 11:30am

Scientists play ping-pong with single electron using paddles made of…

Technically, any sound moves electrons, since electrons are part of the atoms that move in pressure waves. But now scientists are using sonic waves to move an electron down a wire perfectly - with no loss of information. Then they played ping-pong with it. Typical. » 9/22/11 7:40am 9/22/11 7:40am

Exotic nanodevice could let computers ditch slowpoke electrons and run…

Modern computers rely on electrons moving through wires to transmit information, which is far, far slower than the fast-as-light optics we theoretically could be using. And now we've found the exotic material that might allow us to leave electrons behind. » 7/20/10 7:30am 7/20/10 7:30am

Build a better quantum computer with diamond nanocrystals

One big problem holding up the development of quantum computing is building materials. But there might be a solution, and it awesomely involves nitrogen-infused diamond nanocrystals. » 7/01/10 10:30am 7/01/10 10:30am

Why Are Scientists Trying To Create Slow Light?

Achieving faster than light speed is one of the dearest dreams of science (and science fiction). But what about slowing light down? In the last ten years, scientists have done some amazing things by slowing down the speed of light. » 4/08/10 4:00pm 4/08/10 4:00pm

At Last, A Computer That Takes The Measure Of Hydrogen Molecules


Thanks to quantum computing, we now have a fairly precise idea how much energy a hydrogen molecule gives off. Gone are the days when we had to guess this sort of thing by tossing atoms from hand to hand. » 1/23/10 1:00pm 1/23/10 1:00pm

Mathematicians Create Algorithm So Complex No Computer Can Use It...Yet

Quantum computers, which would rely on quantum mechanical concepts like superposition and entanglement to perform operations of unimaginable complexity, remain a pipe dream. But physicists have nevertheless come up with an algorithm that only quantum computers could use. » 1/09/10 8:00am 1/09/10 8:00am

Meet Two New Quantum Particles: Spinons and Holons

The latest development in particle physics reveals the "indivisible" electron might not be so indivisible in all situations. Scientists at Cambridge University have discovered that electrons in quantum-scale wires can break into two smaller particles, called spinons and holons. » 7/31/09 10:51am 7/31/09 10:51am

Super Small, Super Powerful Quantum Processor Can Solve Multiple…

Soon your processor might be able to do three things at once. In a major stride towards commonplace quantum computing, a Yale university team has just unveiled a new two-qubit quantum processor that actually looks like a conventional computer chip. » 6/29/09 3:08pm 6/29/09 3:08pm
