Google began testing a revolutionary new computer system. This kind of computer is millions of times faster than existing computers. It may not only speed up scientific research related to climate and
The Wall Street Journal reported that Google’s flagship product, Google Search, could be of great benefit. A Google spokesperson said that with the help of new technologies, Google search engines will be able to learn and automatically improve their search results in
The quantum computer used by Google is manufactured by Canadian startup D-Wave Systems and is currently installed at the Ames Research Center under NASA. Quantum computers use technology that is completely different from traditional computers. Existing computers use “0” and “1” to complete the calculation, called a bit. But the “qubit” used by quantum computers can represent 0, 1 and any value between 0 and 1, greatly expanding the depth of information processing. In theory, the performance of quantum computers can grow exponentially relative to traditional computers.
Google Inc. said that in a well-designed experiment, preliminary results showed that D-Wave’s 2X model prototype was 100 million times faster than traditional computers. MIT professor Edward Farhi said that Google’s experiments confirmed that the D-Wave prototype is indeed quantum computing, which is very important. Matthias Troyer, a professor at the Federal Institute of Technology (ETH) in Zurich, Switzerland, expressed doubts. He said that the traditional computer used in the Google experiment is not a supercomputer, so the experimental results are biased towards the D-Wave prototype. But Troyer said that Google’s experiments at least confirm that quantum computers are not completely useless and may be useful in the future.
In a blog post, Google acknowledged that existing computers could solve their experimental problems more quickly and said they were improving their experimental solutions. At a press conference earlier this week, Google also revealed some shortcomings of the D-Wave 2X prototype. For example, the prototype can only be designed to perform a specific task; its processor needs to be cooled to near zero to work. Google also revealed that the 2X prototype exploded almost during the last cleaning.
However, both Google researchers and outside experts believe that quantum computers may solve complex multi-parameter problems that traditional computers cannot solve. Google believes that quantum computers may be used in the field of machine learning.
Google is also working on a general-purpose quantum computer capable of performing multitasking. Other computer companies, including IBM, are also working on this. Professor Troyer said that this may take 15-20 years.
