dreamdancer 0 #1 September 4, 2009 multiverse here we come... QuoteA quantum calculation able to crack one of the most common forms of data encryption has been performed on a silicon chip for the first time. The study demonstrates that complex quantum circuits can be built relatively easily out of silicon and silica – a significant milestone on the road to full-blown quantum computing. Fifteen years ago, Peter Shor, a computer scientist at the Massachusetts Institute of Technology, predicted that quantum computers could beat even the most powerful supercomputers and crack the widely used RSA encryption algorithm. Now a proof-of-principle version of Shor's idea has been demonstrated on a silicon chip for the first time. The 26-millimetre-long chip was designed and built using standard fabrication processes by Jeremy O'Brien, Jonathan Matthews and Alberto Politi at the University of Bristol, UK. It can run Shor's algorithm in cut-down form – confirming that 3 and 5 multiply to form 15, which is the simplest possible demonstration. Unlike the silicon chips inside conventional computers, the Bristol team's chip uses light rather than electricity. Light-transmitting silica on a silicon wafer guides photons with entangled quantum properties around, an approach first demonstrated by the same team last year. http://www.newscientist.com/article/dn17736-codebreaking-quantum-algorithm-run-on-a-silicon-chip.htmlstay away from moving propellers - they bite blue skies from thai sky adventures good solid response-provoking keyboarding Quote Share this post Link to post Share on other sites

Dreamdancer seems to have a hard on for quantum computing. Quote Share this post Link to post Share on other sites
georgerussia 0 #6 September 5, 2009 Quote Well the article talks about breaking RSA, but then it looks to be something far less impressive. Dreamdancer seems to have a hard on for quantum computing. Of course. You can break RSA with a computer inside your cell phone, no problem. All you need is basic math functions operating with large numbers - something not difficult to implement. The real question is, how long cracking will take, and that's where it doesn't look like we're getting any improverment.* Don't pray for me if you wanna help - just send me a check. * Quote Share this post Link to post Share on other sites

nanook 1 #11 September 5, 2009 But do you understand what I am getting at? The study of quantum mechanics has existed at least since the 19th century. This multiverse stuff didn't show up in popular science fiction till around the 1940's or so. I think you got your info from the latter, who use fancy science words (like Star Trek) to make a backdrop to a utopic story whose purpose is to show difference between society of today vs. better future society; mostly due to writer's lack of imagination (or financial reward to fill escapism needs). You are not supposed to take those things seriously._____________________________ "The trouble with quotes on the internet is that you can never know if they are genuine" - Abraham Lincoln Quote Share this post Link to post Share on other sites

You are not supposed to take those things seriously. A "multiverse" is indeed a possibility according to current cosmologists' thinking about the interaction of quantum mechanics with relativity.

champu 1 #13 September 7, 2009 Quoteif quantum computers work (which they seem to do from these very early calculations) it pretty much confirms that the multiverse exists and that it is being drawn upon to do the quantum computations. My hang up with the way this article was posted here is that you don't necessarily need an application like the one in the article to prove the principles behind the existence of a multiverse. In fact, along the lines of Tegmark one might jokingly argue that the more specific your application, the less it demonstrates. I find it interesting that someone creates a quantum computer that is another step less academic then the last one, the article is stuck on breaking RSA (who cares? cryptography doesn't have all its eggs in that basket), and everyone's favorite dropzone.com one-man syndication team suggests this "pretty much confirms" a theory in abstract cosmology. I think it demonstrates once again how you can go wrong by looking too high or too low at a problem. Now, on the other hand, if one were to look at a problem from a superposition of both too high and too low simultaneously... Quote Share this post Link to post Share on other sites
