Google Buys a Quantum Computer

“Google and NASA are forming a joint research lab to look at quantum computing for things like facial recognition and understanding of disease. Their computer is from D-Wave Systems, which appears to be producing quantum computing results years earlier than many expected.”>

Google and a corporation associated with 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 post announcing 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 bought the machine 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 will use at NASA’s Ames Research facility, located near Google headquarters, 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.

An earlier version of this story stated that NASA was involved in the purchase of the quantum computer. While the computer will be located at NASA’s facility, it was not involved in the purchase of the computer.


 

 Welcome To The Effingham WiFi News Board, today’s topic

“building a computer”

In our fast pace world we live in today, fast Internet speeds are a must, but we sometimes over look the tools we are using to make that happen. Our Computer is just as important as the antennas!! I have built a lot of  computers over the years, and I like to help you understand the mechanics of a working computer for your next big adventure of building the computer of your dreams.

 With The Effingham WiFi News Board + This instruction will help to guide you to make your own personal desktop computer Special thanks to wikihow and Carey Holzman  for the videos and installations used here today.
There are some steps to follow you. After finishing assembling all components, you will obtain the computer for yourself and you can design a system more targeted toward your own use.


 Step 1

Prepare the Mainboard (motherboard)

  1. Prepare the Mainboard (motherboard) which is the NVIDA model. If you want to assemble the well-liked device, you should use Intel G31, GMA3100, or AMD 780 Mainboard.
  2. Build a Personal Desktop Computer Step 2.jpg

    Mount the CPU in the socket of the Mainboard. You must choose the correct CPU for your motherboard, and install it according to it’s instructions. Be careful not to install the CPU in wrong. Not only would your computer not work, it could short-circuit and damage your motherboard.

  3. Build a Personal Desktop Computer Step 3.jpg

    Connect the CPU cooler to the Mainboard.

  4. Build a Personal Desktop Computer Step 4.jpg

    Attach the RAM(memory) modules in the corresponding slots. the motherboard should have rows of slots that have 2 or 3 sections that are different lengths. Make sure the pins on the RAM cards line up with the pins on the motherboard connector. Don’t get the RAM slots mixed up with PCI slots. The PCI slots are usually wider.

  5. Build a Personal Desktop Computer Step 5.jpg

    Open the case and mount the power supply which is M-ATX type. Make sure to connect all the connections to the drives and the motherboard.

  6. Build a Personal Desktop Computer Step 6.jpg

    Attach the Mainboard back plate to the case and check the Mainboard mounting positions. The motherboard’s instructions should tell the position of the motherboard.

  7. Build a Personal Desktop Computer Step 7.jpg

    Suitably position the Mainboard in the case.

  8. Build a Personal Desktop Computer Step 8.jpg

    Mount the Hard disk and connect it to the power supply and the motherboard. There should be separate connections for the power supply and the motherboard. In SATA Hard disk case, should remove the jumper.

  9. Build a Personal Desktop Computer Step 9.jpg

    Connect the SATA connectors to the drives and the USB connectors and the case switches to the motherboard. The case and motherboard’s instructions should tell where to connect the cables. [[Image:Step9_790.JPG|300px|]

  10. Build a Personal Desktop Computer Step 10.jpg
    10

    Connect the 20 or 24 pin ATX connector and the 4-pin power supply control connector to the motherboard.

  11. Build a Personal Desktop Computer Step 11.jpg
