Good, because the latest news published in Nature is that diamonds are a quantum computer's best friend -- particularly if they're flawed. An international team of scientists sought out sub-atomic impurities in a 1mm-thick fragment of over-priced carbon and used these as qubits to perform successful calculations. A "rogue" nitrogen nucleus provided one qubit, while a free electron became a second. Unlike previous attempts at solid-state quantum computing, this new effort used an extra technique to protect the system from decoherence errors: microwave pulses were fired at the electron qubit to "time-reverse" inconsistencies in its spinning motion. Don't fully get it? Us neither. In any case, it probably won't stop jewellers tut-tutting to themselves.

You're not alone, as rising concerns surrounding the security of distributed computing have led University of Vienna researchers to seek out quantum mechanics as a privacy fix. The team's findings, soon to be published in the journal Science, prove that an end user's data can remain encrypted throughout its journey to and from remote servers, essentially rendering the quantum computer's calculations as "blind." So, how exactly does this evasive entanglement work? Qubits (or quantum bits) containing the pertinent information are transmitted to a central facility where they're processed according to a specific set of measurements, leaving the resultant computations readable only by the original user. Not obtuse enough for you? Then check out the source below for a more detailed walkthrough.

By tapping into Albert Einstein's idea of "spooky action at a distance," researchers at the University of Copenhagen's Niels Bohr Institute have discovered what might be the key to completely secure data transfer -- keeping particles "entangled" for up to an hour. Until now, the link between two entangled systems could only be maintained for a fraction of a second. This development could enable a direct link between two systems of communication -- you do something to one and the other will "know." Although limited to the lab right now, scientists are working on practical applications for networking and the internets. Hey, SSH maybe it's time you started watching your back. Check out the full PR after the break.

That hasn't stopped anyone from trying to validate its corollaries, and in the interim, researchers like Michael Duff of the Imperial College London. Mr. Duff realized a few years ago there existed some strong relations between formulas pertaining to both black holes (relativity) and four entagled qubits (quantum mechanics). So, in his words, "In a way, there's bad news and good news in our paper. The bad news is, we're not describing the theory of everything. The good news is, we're making a very exact statement which is either right or wrong. There's no in between." We're sure some science cliques are already gearing up to get their troll on. Hit up the PDF below if you want to read it yourself.

It's the basis for the latest approach to gather steam in the never-ending quest to endue touchscreens with force recognition, and its promises are as lofty as you'd expect. Developed by UK researchers Peratech, this new methodology revolves around a 75-micrometer (less than a tenth of a millimeter) quantum tunneling composite, which display makers can add to their screens relatively cheaply and painlessly. The pressure-sensing layer consumes no power when it isn't depressed and requires a miniscule two micrometers of movement to register a touch. Japanese display maker Nissha (who counts LG and Nintendo among its customers) has grabbed a license and we're even hearing devices could be coming out as soon as April. Check the Peratech site for more info.
