'Flip-flop' design makes quantum computers more affordable
One of the greatest challenges in quantum computing is... well, making the computers. You may need exotic manufacturing techniques just to handle the very exacting requirements, such as positioning the atoms in quantum bits in exact positions at close distances (to make quantum entanglement happen). However, that might not be a problem going forward. Australian researchers have developed a new chip design that could be built using the same silicon technology that you see in use today.
Study: Men who harass women online suck at games (and life)
Researchers think that they've worked out why certain men abuse women over the internet: because they suck... at games. According to a study by Michael Kasumovic and Jeff Kuznekoff, the most vocal abusers of women online are the ones most threatened by their presence in the digital sphere. The short explanation for this is because less-skilled men have the most to lose playing games against a woman, thanks to the perceived social stigma of "losing to a girl." Rather than risk this supposed humiliation, they'd much rather create a toxic environment that's outright hostile to newcomers.
New single ion clock is '100 times more precise' than existing atomic models
Researchers at the University of New South Wales have developed a new type of atomic clock that measures an atom's neutron orbit instead of the electron's flight path. This method is apparently accurate to 19 decimal places, with several lasers shifting electrons in a certain way, allowing Professor Victor Flambaum to measure the "pendulum" motion of the neutron. It's purportedly close to 100 times more precise than its predecessors -- all with no freezing involved. These existing atomic clocks may be accurate beyond 100 million years, but for this new breed of hyper-accurate timekeeping, you'll only need to reset the clock once every 14 billion years. And we have no idea how they calculated that.
Single atom transistors point to the future of quantum computers, death of Moore's law
Transistors -- the basic building block of the complex electronic devices around you. Literally billions of them make up that Core i7 in your gaming rig and Moore's law says that number will double every 18 months as they get smaller and smaller. Researchers at the University of New South Wales may have found the limit of this basic computational rule however, by creating the world's first single atom transistor. A single phosphorus atom was placed into a silicon lattice and read with a pair of extremely tiny silicon leads that allowed them to observe both its transistor behavior and its quantum state. Presumably this spells the end of the road for Moore's Law, as it would seem all but impossible to shrink transistors any farther. But, it could also points to a future featuring miniaturized solid-state quantum computers.
First light wave quantum teleportation achieved, opens door to ultra fast data transmission
Mark this day, folks, because the brainiacs have finally made a breakthrough in quantum teleportation: a team of scientists from Australia and Japan have successfully transferred a complex set of quantum data in light form. You see, previously researchers had struggled with slow performance or loss of information, but with full transmission integrity achieved -- as in blocks of qubits being destroyed in one place but instantaneously resurrected in another, without affecting their superpositions -- we're now one huge step closer to secure, high-speed quantum communication. Needless to say, this will also be a big boost for the development of powerful quantum computing, and combine that with a more bedroom friendly version of the above teleporter, we'll eventually have ourselves the best LAN party ever.
Bionic eye closer to human trials with invention of implantable microchip
We've had our eye -- so to speak -- on Bionic Vision Australia (BVA) for sometime, and with the invention of a new implantable microchip it's coming ever closer to getting the bionic eye working on real-deal humans. The tiny chip measures five square millimeters and packs 98 electrodes that stimulate retinal cells to restore vision. Preliminary tests are already underway, and clinicians are in the process of screening human guinea pigs for sampling the implants -- the first full system is still on track for a 2013 debut. In the interest of future success: here's mud in your eye, BVA! Full PR after the break.
Sunswift IV, world's fastest solar-powered racer, leaves GM Sunraycer in its dust
The Sunswift IV (aka IVy) might look like a mobile dinner table, but it's actually the world's fastest solar-powered vehicle. The table-top on wheels got the official nod from the Guinness Book of World Records last week, for hitting a top speed of 88km/h (about 55 mph) -- nearly 10 km/h faster than the previous record-holder, the GM Sunraycer, which bears a striking resemblance to a disembodied Android monster. IVy, designed by Sunswift, a student-run non-profit at the University of New South Wales, reached its top speed using 1050 watts, about 400 watts less than the Sunraycer, and performed its record-smashing run without the 25kg battery it's usually packing. Faster runs have been clocked, including by IVy, but Guinness has not been on hand for confirmation.
Researchers develop means to reliably read an electron's spin, take us one step closer to the quantum zone
Another day, another step bringing us closer to the next big revolution in the world of computing: replacing your transistory bits with qubits. Researchers at Australia's Universities of New South Wales and of Melbourne, along with Finland's Aalto University, have achieved the impossibly tiny goal of reliably reading the spin of a single electron. That may not sound like much, but let's just see you do it quickly without affecting said spin. This particular implementation relies on single atoms of phosphorus embedded in silicon. Yes, silicon, meaning this type of qubit is rather more conventional than others we've read about. Of course, proper quantum computers depend on reading and writing the spin of individual electrons, so as of now we effectively have quantum ROM. When will that be quantum RAM? They're still working on that bit.
