Meet the companies racing to build quantum chips

The quantum calculation has long been announced as “right around the corner”, but several companies are now determined to make this commercial reality, with the promise of solving complex problems beyond the reach of classic computers.

The problems concerned are wide, from medicine and cyber security to the science of materials and chemistry. But first, there are very practical problems that need to be solved, such as the development of chips that can reliably host a large number of quit – short for quantum bits, the basic units of information in quantum computer science.

As usual in high -level technological race with an insecure time horizon, technological giants like Google and Microsoft are headed. However, the startups are also set up to play an important role, especially in solving narrow heads such as the correction of the connection and correction of errors that are critical for scaling of quantum systems.

But some startups and less technological companies are taken over by Chip Challenge Head-on and deserve mentioning together with more effort to attract attention from industrial giants. Although large technological projects are usually boasting of the largest number of quit, the reconsideration of design from the first principles and the use of different approaches could give equally promising results.

Here are some companies behind the main quantum chip projects that are worth watching:
