D-Wave 512-Qubit Bonded Processor – Recent Generation
Earlier this week, I was advised by a VC friend in Vancouver to expect another blockbuster announcement from D-Wave. And so it has happened. As if to stem any further skepticism and debate about D-Wave’s quantum computing technology, Google today announced that it has bought a D-Wave quantum computing system, in a partnership with NASA and Lockheed Martin Aerospace. This is the second major sale of a D-Wave system, and further evidence that this is not simple tire kicking by a group of ivory tower scientists.
Of particular note to me personally, was the growing significance of Vancouver as a site for a exceedingly advanced startup like D-Wave. In my previous post on this subject, I questioned whether a company in such a rarified area could attract the necessary personnel here. Twenty years ago, when Mobile Data International started, I was one of four Americans to cast our fates to the wind and move to Canada to join MDI. At that time, we were seen as completely out of our minds. Vancouver had no attraction or other high tech industry companies worthy of note. Today, Vancouver is seen as an World Class City, and one of the most livable. This may be one of the most important issues in favour of a growing high tech industry in Vancouver.
By way of example, it was also announced in parallel today that two key people from Silicon Graphics, the precursor in some respects to D-Wave, Bo Ewald, former SGI CEO, and Steve Cakebread, former SGI financial officer, have joined D-Wave. Apparently, Ewald will lead D-Wave’s U.S. subsidiary company, and Cakebread has relocated to Vancouver. If you have ever seen a bottle of Cakebread Cellars Chardonnay in a BC Liquor store, it is the same Steve Cakebread that is responsible. More importantly, Vancouver may now be able to attract the kind of talent needed for companies like D-Wave.
Google and NASA are forming a laboratory to study artificial intelligence by means of computers that use the unusual properties of quantum physics. Their quantum computer, which performs complex calculations thousands of times faster than existing supercomputers, is expected to be in active use in the third quarter of this year.
The Quantum Artificial Intelligence Lab, as the entity is called, will focus on machine learning, which is the way computers take note of patterns of information to improve their outputs. Personalized Internet search and predictions of traffic congestion based on GPS data are examples of machine learning. The field is particularly important for things like facial or voice recognition, biological behavior, or the management of very large and complex systems.
“If we want to create effective environmental policies, we need better models of what’s happening to our climate,” Google said in a blog postannouncing the partnership. “Classical computers aren’t well suited to these types of creative problems.”
Google said it had already devised machine-learning algorithms that work inside the quantum computer, which is made by D-Wave Systems of Burnaby, British Columbia. One could quickly recognize information, saving power on mobile devices, while another was successful at sorting out bad or mislabeled data. The most effective methods for using quantum computation, Google said, involved combining the advanced machines with its clouds of traditional computers.
Google and NASA bought in cooperation with the Universities Space Research Association, a nonprofit research corporation that works with NASA and others to advance space science and technology. Outside researchers will be invited to the lab as well.
This year D-Wave sold its first commercial quantum computer to Lockheed Martin. Lockheed officials said the computer would be used for the test and measurement of things like jet aircraft designs, or the reliability of satellite systems.
The D-Wave computer works by framing complex problems in terms of optimal outcomes. The classic example of this type of problem is figuring out the most efficient way a traveling salesman can visit 10 customers, but real-world problems now include hundreds of such variables and contingencies. D-Wave’s machine frames the problem in terms of energy states, and uses quantum physics to rapidly determine an outcome that satisfies the variables with the least use of energy.
In tests last September, an independent researcher found that for some types of problems the quantum computer was 3,600 times faster than traditional supercomputers. According to a D-Wave official, the machine performed even better in Google’s tests, which involved 500 variables with different constraints.
“The tougher, more complex ones had better performance,” said Colin Williams, D-Wave’s director of business development. “For most problems, it was 11,000 times faster, but in the more difficult 50 percent, it was 33,000 times faster. In the top 25 percent, it was 50,000 times faster.” Google declined to comment, aside from the blog post.
The machine Google and NASA will use makes use of the interactions of 512 quantum bits, or qubits, to determine optimization. They plan to upgrade the machine to 2,048 qubits when this becomes available, probably within the next year or two. That machine could be exponentially more powerful.
Google did not say how it might deploy a quantum computer into its existing global network of computer-intensive data centers, which are among the world’s largest. D-Wave, however, intends eventually for its quantum machine to hook into cloud computing systems, doing the exceptionally hard problems that can then be finished off by regular servers.
Potential applications include finance, health care, and national security, said Vern Brownell, D-Wave’s chief executive. “The long-term vision is the quantum cloud, with a few high-end systems in the back end,” he said. “You could use it to train an algorithm that goes into a phone, or do lots of simulations for a financial institution.”
Mr. Brownell, who founded a computer server company, was also the chief technical officer at Goldman Sachs. Goldman is an investor in D-Wave, with Jeff Bezos, the founder of Amazon.com. Amazon Web Services is another global cloud, which rents data storage, computing, and applications to thousands of companies.
This month D-Wave established an American company, considered necessary for certain types of sales of national security technology to the United States government.
