Google bought one. So did Lockheed Martin, one of the world’s largest defense contractors. But we still can’t agree on what it is they bought.
D-Wave, the company that built the thing, calls it the world’s first quantum computer, a seminal creation that foretells the future of mathematical calculation. But many of the world’s experts see it quite differently, arguing the D-Wave machine is something other than the computing holy grail the scientific community has sought since the mid-1980s.
No doubt, the argument will continue. But today, researchers at the University of Southern California published a paper that comes that much closer to showing the D-Wave is indeed a quantum computer. USC houses and operates the D-Wave system owned by Lockheed, and the researchers — led by Daniel Lidar, a professor of electrical engineering, chemistry, and physics — say they have at least shown the machine is not using a computing model known as “simulated annealing,” which obeys the laws of classical physics (the physics of everyday life) rather than the more elusive properties of quantum physics.
“[Our research] rules out one type of classical model that has been argued as a proper description of the D-Wave machine,” Lidar says. “A lot of people thought that when D-Wave came on the market their machine was just doing that, [but] we ruled that out.”
The paper, Experimental Signature of Programmable Quantum Annealing, appears in the well-respected academic journal Nature Communications. Quantum annealing is a computing model that, yes, operates in the quantum realm, and according to Lidar, the team’s research shows “a very great agreement” between quantum annealing and the way the D-Wave system operates.
Google has announced that failure to fix annoying mobile experiences will now actively hinder your efforts to rank well within search results. This warning from Google makes the case for brands to look again at mobile SEO even more compelling.
We’ve all been there — that moment in any link building campaign where you hit a wall. There are so many things that you want to do, but there is so little time or buy-in to do them that you settle on just doing the things you need to do.
Quite a few things have changed in my approach to link building since my first link building guide back in 2010. For starters, there was a mass of link based algorithm updates, there was Penguin, and to top this all off I’ve changed jobs as well (you can find me amongst the masses here these days). One thing that hasn’t changed is my view that 80% of positive (and negative) SEO ranking factors still come from external sources – I’m not just talking about links here, but social and citations, also.
The most compelling feature of Google+ is the Hangout. Read on to find out what the value is for using Google+ Hangouts as part of your marketing mix.
The value of these Hangouts can be proven by using the four categories of measurement that I have determined to define success:
Content – Struggling for fresh content? Hangouts are awesome for providing content, and content that can be repurposed. The Hangout recording syncs to Youtube and can then be embedded back into Google+, a blog or even a landing page. Transcribing the hangout can make for a great blog post as well.Engagement – The Hangouts that we hosted earned thousands of social signals in the form of shares/ +1/ comments etc. Better yet, some of these were from influencers in our space, which leads to better visibility while increasing the relevance that these signals show around our content to Google.SEO – Everything that is shared on Google+ has the potential of showing up in Google search. The more people who are sharing and engaging with your posts and content, the better chance you have of ranking in search. This is especially relevant for personalized results, but there is also evidence that it affects search rankings in general.Thought Leadership – Hanging out with influential folks from your industry and interviewing them live on air is a fantastic way to build thought leadership. Not only are you providing a platform for external thought leaders, but you are also building up your own influence.
Hangouts are in no position to replace a webinar platform, but hosting one is a great way to experiment and have fun within what is essentially your own television studio for the web.

An infographic on how to audit your site in light of Google's Penguin update.
Google’s Penguin update was aimed at decreasing search engine rankings of websites that violate Google’s guidelines by using black-hat SEO techniques such as keyword stuffing, cloaking, participating in link schemes, and the deliberate creation of duplicate content. The update has also affected sites not engaged (knowingly) in black-hat SEO. From Search Engine Journal and Link-Assistant.com, here's an infographic on how to do a Penguin-savvy inventory of your site, including:
