Photon entanglement is one of the odder properties of quantum physics, but it promises a lot for computing -- if one photon can instantly affect another no matter how far away it is, you could make super-speedy computers and communications that aren't easily limited by physical distances. It hasn'...

It's a spooky feature of Grand Central Station that if you whisper something against the wall, your voice can resonate around the perimeter of the building and sneak up on you from behind. The same 'whispering gallery' principle is crucial to next-gen optical computing: light signals have to be s...

The trouble with pesky Photon, at least as far as ultra-fast optical computing is concerned, is that he keeps coming back. If a data-carrying beam of light collides with reflections bouncing around between the components of a chip, it can suffer enough interference to make people yearn for the go...

Fujitsu just announced what's reportedly the world's first quantum dot laser capable of 25 gigabits per second of data transmission. Go on -- there's no need to hold your applause. Now, we've seen lasers beam packets at 1.2 terabits per second over miles of open ground, and up to 15.5Tbps through a...

LED data transmission used to be all the rage -- we fondly remember beaming Palm Pilot contacts via IrDA. Then we got omni-directional Bluetooth and building-penetrating WiFi, and put all that caveman stuff behind us. But now, scientists the world over are looking to bring back line-of-sight netw...

Bandwidth scarcity, is there any more pressing global issue that we're faced with today? We think not. Given the exponential growth in both computing power and software's exploitation and expectation of greater resources, it's no surprise that at some point we'll have to look beyond simple electrica...

We tend to prefer our electronics to be as far from invasive as possible, and that definitely includes cabling. While we'd take wireless over the corded approach any day, tethered applications still have their place, and a diminutive new cable is showing bigtime promise in a few prominent fields. A...
