D-Wave’s quantum computer overcomes key math challenge, doesn’t silence skeptics
Posted in: Today's Chili
D-Wave has long wanted to show that its quantum computing technology is the real deal, and it may have just come closer to proving its case. The company now says that its computer has calculated Ramsey numbers, or solutions to optimization-based math problems that are sometimes difficult to find using traditional systems. The computation represented one of the biggest-ever implementations of an algorithm, according to researchers. However, the feat isn’t necessarily proof of quantum computing at work. As Wired explains, we’ve seen all of these numbers in previous experiments; the challenge wasn’t difficult enough to require the involvement of a quantum computer. However, D-Wave may have better evidence in the future. Its third-generation system, due in 2015, should have enough power to find Ramsay numbers that are theoretically impossible to calculate today.

D-Wave has had little trouble lining up customers for its quantum computer, but questions have persisted as to whether or not the machine is performing quantum math in the first place. University of Southern California researchers have tested Lockheed Martin’s unit to help settle that debate, and they believe that D-Wave’s computer could be the real deal — or rather, that it isn’t obviously cheating. They’ve shown that the system isn’t based on simulated annealing, which relies on traditional physics for number crunching. The device is at least “consistent” with true quantum annealing, although there’s no proof that this is what’s going on; it may be using other shortcuts. Whether or not D-Wave built a full-fledged quantum computer, the resulting output is credible enough that customers won’t feel much in the way of buyer’s remorse.

Google and NASA team up for D-Wave-powered Quantum Artificial Intelligence Lab
Posted in: Today's Chili
Google. NASA. Quantum computers. Seriously, everything about the new Quantum Artificial Intelligence Lab at the Ames Research Center is exciting. The joint effort between Mountain View and America’s space agency will put a 512 qubit machine from D-Wave at the disposal of researchers from around the globe, with the USRA (Universities Space Research Association) inviting teams of scientists and engineers to share time on the unique super computer. The goal is to study how quantum computing might be leveraged to advance machine learning, a branch of AI that has proven crucial to Google’s success. The internet giant has already done some work with quantum computing before, now the goal is to see if its experimentation can translate into real world results. The idea, for Google at least, is to combine the extreme (but highly-specialized) power of the quantum bit with its oceans of traditional data centers to build more accurate models for everything from speech recognition to web search. And maybe, just maybe, with the help of quantum computers your phone will finally realize you didn’t mean to say “duck.”
