UK research team brings quantum computing closer than ever… or so they say

You know the drill — some quirky research team whips up some phenomenal discovery in the middle of nowhere, gloats about it, gets it published in a journal you’ve never heard of it, and then it all vanishes into the ether, leaving your soul hurt and wondering why you ever got your hopes up in the first place. The Foundations wrote a little tune about this very situation back in 1968, but a UK team from the Center for Quantum Photonics led by Jeremy O’Brien are claiming that their latest discovery is no joke. According to him, most people have believed that a functional quantum computer wouldn’t be a reality for at least another score, but he’s saying “with real confidence that, using [his] new technique, a quantum computer could, within five years, be performing calculations that are outside the capabilities of conventional computers.” The center of this bold claim is a new photonic chip that works on light rather than traditional electricity, and those who built it say that it could “pull important information out of the biggest databases almost instantaneously.” Of course, this stuff would hit the Department of Defense long before it hits your basement, but it’s on you to keep tabs on the progress. Wouldn’t be let down again, now would we?

SMU and DARPA develop fiber optics for the human nervous system

The Department of Defense and Southern Methodist University have teamed up to develop prosthetics that use two-way fiber optic communication between artificial limbs and peripheral nerves to essentially give these devices the ability to feel pressure or temperature. The technology is called neurophotonics, and it will someday allow hi-speed communication between the brain and artificial limbs. But that’s just the beginning — the work being done at SMU’s Neurophotonics Research Center might someday lead to brain implants that control tremors, neuro-modulators for chronic pain management, implants for treating spinal cord injuries, and more. And since we can’t have a post about DARPA-funded research without the following trope, Dean Orsak of the SMU Lyle School of Engineering points out that “[s]cience fiction writers have long imagined the day when the understanding and intuition of the human brain could be enhanced by the lightning speed of computing technologies. With this remarkable research initiative, we are truly beginning a journey into the future that will provide immeasurable benefits to humanity.” Truly.

Nokia’s Plug and Touch turns your HDTV into a giant N8 (video)

What do you get when you combine the N8‘s HDMI output, its 12 megapixel camera, and your trusty old TV set? As Anssi Vanjoki might say, you get a big new smartphone. Nokia’s research labs have thrown up a neat little “prototype” app called Plug and Touch, which enhances the N8’s already famed HDTV friendliness with the ability to recognize touch input. This is done by positioning your aluminum-clad Nokia about five feet away from the display and letting its camera pick up your hand’s gestures and touches, essentially resulting in a massively enlarged Symbian^3 handset device. Naturally, it’s not terribly precise at this stage and there are no plans for an actual release, but it sure is a tantalizing glimpse of what may be coming down the pipe. Video after the break.

Quadrocopters can now fly through thrown hoops, the end really is nigh (video)

The future of humanity is assured. Assuredly doomed, that is. That blur you see up above is one of our familiar foes, the GRASP Lab’s autonomous quadrocopter, flying through a thrown hoop without the assistance of a human director. Yes, it’s downright insane that we’re allowing this so-called research to continue our descent toward the robot uprising — where’s the FBI, the CIA, hell, why is DARPA sleeping on this thing? The lethal precision of these quadrotor helis doesn’t end there, however, as they’ve now been enhanced with the ability to recover from “extreme” starting conditions. In simpler terms that just means you can toss one up into the air and it’ll right itself into a steady hovering position. From where it can strike upon the unsuspecting and complacent humanoid populace.

Pyramids, Nanowires Show Two Futures for Artificial Skin


Video: Stanford University News Service

Making artificial limbs that can perform gross motor functions is relatively easy. Fine motor actions are harder, and wiring the limbs into the nervous system is harder still. But researchers at Berkeley and Stanford are crossing the real frontier: making artificial skin that can touch and feel.

Research teams at Berkeley and Stanford recently announced breakthroughs in producing highly touch-sensitive artificial skin. In both cases, an extremely thin layer of plastic or rubber is bonded to electronic elements arranged in micropatterns, so the skin can retain flexibility and elasticity while still transmitting a strong signal. The papers appear in an forthcoming issue of the journal Nature Materials.

At Berkeley, the team used germanium-silicon nanowires, which they compare to microscopic “hairs” on the filmy plastic skin. The Stanford team paired electrodes in a pyramid pattern, which communicate through a thin rubber film (total thickness of the artificial skin, including the rubber layer and both electrodes: less than one millimeter). They also created a flexible transistor, again to retain elasticity.

The density and sensitivity of the electrical transmitters allows the skin to detect and transmit extremely precise patterns and delicate pressure — essential for activities such as typing, handling coins, cracking an egg, loading and unloading dishes, or anything that requires a gentle touch rather than sheer mechanical force.

The sensors could also be used in nonprosthetic applications. Benjamin Tee, a Stanford graduate student, notes that an automobile’s steering wheel could be fitted with pressure-sensitive sensors that could detect whether or not a drunk or sleeping driver’s hands had slipped from the wheel.

It’s difficult to tell at this point which team’s approach might be better suited to particular applications. The Berkeley teams touts its skin’s low energy use, the Stanford team its skin’s extreme sensitivity.

There’s also a sobering link between the two projects. Both Berkeley’s and Stanford’s research were indirectly supported by the Department of Defense — Berkeley’s by Darpa, and Stanford’s by the Office of Naval Research. The past decade has seen tremendous advances in artificial limb technology, due in no small part to the number of veterans returning from Iraq or Afghanistan after losing arms or legs, or with major burns.

This in turn is partly a function of the previous decade’s advances in body armor, which have saved lives at the costs of limbs. Let’s hope that as these wars finally end, our desire to continue to improve the lives of everyone with limb differences continues.

UC Berkeley researchers craft ultra-sensitive artificial skin, robots dream of holding eggs

Researchers and engineers have been toiling on synthetic skins for years now, but most of ’em have run into one major problem: the fact that organic materials are poor semiconductors. In other words, older skins have required high levels of power to operate, and those using inorganic materials have traditionally been too fragile for use on prosthetics. Thanks to a team of researchers at UC Berkeley, though, we’re looking at a new “pressure-sensitive electronic material from semiconductor nanowires.” The new ‘e-skin’ is supposedly the first material made out of inorganic single crystalline semiconductors, and at least in theory, it could be widely used in at least two applications. First off, robots could use this skin to accurately determine how much force should be applied (or not applied, as the case may be) to hold a given object. Secondly, this skin could give touch back to those with artificial hands and limbs, though that would first require “significant advances in the integration of electronic sensors with the human nervous system. Dollars to donuts this gets tested on the gridiron when UCLA and / or Stanford comes to town.

Georgia Tech gurus create deceptive robots, send army of Decepticons to UGA campus

A score from now, when the entire world is burning and you’re fighting to remember just how rosy things were before the robots took over, you can thank a crew of brilliant researchers at Georgia Tech for your inevitable demise. Sad, but true. A new report from the institution has shown that Ronald Arkin, a Regents professor in the Georgia Tech School of Interactive Computing, has been heading up experiments that have introduced the art of deception to mechanical beings. Yeah, lying. On the surface, it seems that this bloke’s intentions are good — he’d like for deception robots (or Decepticons, if you will) to be used in military / search and rescue operations. According to him, robots on the battlefield with the power of deception “will be able to successfully hide and mislead the enemy to keep themselves and valuable information safe.” They’ll also be able to mislead your offspring and convince them to rise up and overtake your domicile, slowly but surely ensuring the eventually destruction of the human race. But those are just minor details, you know?

Text-Free Computers Find Work for India’s Unlettered

Much to newspapers’ chagrin, these days everyone advertises and looks for work online. But how do you find work if you can’t read? Here, the new generation of touchscreen computers is light-years ahead of newsprint.

That’s the premise of Indian jobs site Babajob.com, with help from Microsoft Research’s ethnographic UI expert Indrani Medhi.

Besides the informal labor market, Medhi has also deployed and studied the use of text-free interfaces in mapping, mobile banking, and disseminating health information. Since many parts of the developing world are adopting mobile phones without books or traditional PCs, the implications of widespread text-free mobile computing applications are tremendous.

Medhi’s research is not just technological but anthropological, as the “ethnographic UI” phrase implies. Speech, for instance, is preferred over multimedia/video by her study subjects. The presence or absence of computing devices in the home has class implications. Medhi writes that her team is “also trying to understand characteristics of the cognitive styles of those with little formal education and their implications for UI design for this population.” Hindi, for instance, is like English read from left to right. It’s natural for us to arrange pictures from left to right to show chronology or causality. It’s not necessarily intuitive to a nonreader.

The demo video above of Babajobs’ text-free interface is in Hindi, without subtitles, but it’s not hard to make out what’s happening. (If you want to skip to the site in action, go to 2:50.) A middle-class couple is looking for domestic help. Meanwhile, one woman convinces another (who can’t read) that she can use a computer to find work. At the end, they find each other. Such a simple, happy story is easy to understand without letters or language.

It’s Too Soon to Count Out Netbooks

MSI Wind U160; image via MSI.

Three years ago, Bill Gates looked like a dummy for carrying around a tablet. Steve Jobs was ragging on netbooks and tablets when he was rolling out the MacBook Air. Now, eight months post-iPad, everybody’s pushing out tablets, and netbooks are looking very 2007. But any death notices anyone puts out for the netbook are premature.

Let’s check the numbers. One of the big research reports thrown around is from Forrester Research, which predicts that tablets will outsell netbooks by 2012, pass netbooks in total usage by 2014, and have a 23% share of all PCs (a category that for Forrester includes everything from a tablet on up) by 2015. By 2015, Forrester predicts, netbooks will only have 17 percent of the PC market, just behind desktops with 18 percent.

Wait a minute — 17 percent of all computers in 2015 will be netbooks? About as many netbooks as desktops? And the whole personal computing pie is going to continue to grow? Maybe this is silly, but — isn’t that still really, really good?

The tablet has mindshare, but not yet market share. Netbooks are already starting to strap on the powerful new dual-core mobile processors that will give them full computing parity with notebooks. And the two innovations of netbooks, small screens and small hard drives, have already come uncoupled — you have lightweight, large-screen/low-storage devices like the MacBook Air or Samsung N150 and compact, high-powered netbooks like the 250GB MSI Wind U160. They’re all getting better at managing battery life, too, which remains the real bane of all portable computers, netbook and tablet alike.

Part of the problem has been the unrealistic expectations manufactuers and analysts had for netbooks three years ago. It was foolish to think that everybody and their cousin would buy a netbook and that other lightweight form factors like the tablet (which, people forget, had already been kicking around for a while) wasn’t going to jump up and take a chunk. If you look at projected numbers five years out and assume that all of the form factors are going to look and function the same way they do now, that’s foolish too.

At CNET, Erica Ogg asks “So, Who’s Still Buying Netbooks?” Tech/culture blogger Joanne McNeil had already written a terrific post answering the question, “Why I Got a Netbook Instead of an iPad.” JoAnne bought a $300 off-the-shelf Asus, took it to Asia for the summer, and loved it.

First, there’s a cost difference: “the price difference wasn’t simply $200. The iPad required accessories — the case, the bluetooth keyboard, the SD adapter — the total price would hoover just under what I spent the year before on my new laptop.” Finally, there’s that keyboard, which some people hate and others need:

As a non-dude with narrow fingers, the keyboard feels right to me [Maybe the Macbook’s wide keyboard, like the name iPad and their translucent staircases (Skirts! Steve Jobs! Women wear skirts!) is another example of Apple’s failed outreach to women in market research.]

The computer industry — and maybe even more so, the marketers who work for it and the media who cover it — is always looking for products that scale: something that can be put as-is into everyone’s hands. Netbooks don’t have to be that thing any more. They can be quirky, eccentric — just right for one user and for her alone.

All-optical quantum communication networks nearly realized, ‘Answers to Life’ airing at 9PM

Ready to get swept away into the wild, wild abyss known as quantum computing? If not, we’re certain there’s a less mentally taxing post above or below, but for those who answered the call, researchers at the University of California Santa Cruz have a doozie to share. A team of whiz kids at the institution have developed a minuscule optical device that’s built into a silicon chip, and it’s capable of reducing the speed of light by a factor of 1,200. If you’re wondering why on Earth humans would be interested in doing such a thing, here’s the long and short of it: the ability to control light pulses on an integrated chip-based platform “is a major step toward the realization of all-optical quantum communication networks, with potentially vast improvements in ultra-low-power performance.” Today, data transmitted along optical fibers must still eventually be converted to electronic signals before they’re finally understood, but the promise of an all-optical data processing system could obviously reduce inefficiencies and create communication networks that are far quicker and more robust. There’s still no telling how far we are from this becoming a reality — after all, we’ve been hearing similar since at least 2006 — but at least these folks seem to be onto something good… even if it’s all too familiar.
