World's First Programmable Quantum Photonic Chip

MrSeb writes “A team of engineering geniuses from the University of Bristol, England has developed the world’s first re-programmable, multi-purpose quantum photonic computer chip that relies on quantum entanglement to perform calculations. With multiple waveguide channels (made from standard silicon dioxide), and eight electrodes, the silicon chip is capable of repeatedly entangling photons. Depending on how the electrodes are programmed, different quantum states can be produced. The end result is two qubits that can be used to perform quantum computing. Most importantly, though, unlike existing quantum photonic setups which require apparatus the size of a ‘large dining table,’ this new chip is tiny: just 70mm (2.7 inches) by 3mm.”

LightSquared Disrupts 75% of GPS Connections In Government Test

Freddybear writes with this quote from BusinessWeek:
“Philip Falcone’s proposed LightSquared Inc. wireless service caused interference to 75 percent of global-positioning system receivers examined in a U.S. government test, according to a draft summary of results. … The tests worked off an ‘extraordinarily conservative’ threshold and didn’t show the devices’ performance was affected, [LightSquared exec Martin Harriman said]. ‘If we’re affecting the performance of the device — my goodness, we’d like to be sure that doesn’t happen,’ Harriman said. The laboratory testing was performed for the National Space-Based Positioning, Navigation, and Timing Systems Engineering Forum, an executive branch body that helps advise policy makers on issues around GPS. It found that 69 of 92, or 75 percent, of receivers tested ‘experienced harmful interference’ at the equivalent of 100 meters (109 yards) from a LightSquared base station.”

Zalman reportedly entering the graphics card market, merging GPUs with cooling solutions

Recently leaked slides suggest Korean computer outfit Zalman will soon jump into the ever-expanding graphics card market, initially partnering with AMD on its Radeon series. Known best for its quiet computing technologies, the company’s move to infuse GPUs with cooling solutions could enhance the performance of the cards, making overclocking a lesson in simplicity. The slides only show the AMD 6870, 6850, and 6770, but it’s feasible more models will appear when official news is released. Given AMD’s many board partners, differentiation is important to remain competitive and on their payroll — graphics cards and their overheating habits is Zalman’s cup of tea. Hopefully this brings more innovative products in the coming future (heck, we’ve already got GPU / NIC hybrids), perhaps as early as CES. Check past the break to view the specifications breakdown for the aforementioned cards.

Kindle Touch Gets World's Simplest Jailbreak

Nate the greatest writes “Can you play an MP3 file? Then you can jailbreak the new Kindle Touch. A new hack was posted this morning that roots the Kindle Touch/K5 and opens the way for future hacks. The hacker also reveals that the K5 runs on HTML5, which should make it a lot easier to come up with new apps. Epub, anyone?”
