Tech giant Google has announced that it has proof that the controversial idea of quantum computing works. The company said the machine dubbed D-Wave, which it purchased way back in 2013, can use quantum physics in number crunching that is essential in artificial intelligence.

Government and top tech companies like IBM, Google and Microsoft are trying to develop the technology behind quantum computers. The companies believe that once they unlock the secret behind quantum computing, they can have access to immense data crunching powers.

For tech companies, quantum computing can greatly make artificial intelligence software more powerful and has great application in the field of science. The National Aeronautics and Space Administration is hoping that quantum computing could help schedule rocket launches as well as simulate future missions and spacecraft.

NASA director of exploration technology at Ames Research Center Rupak Biswas said in a statement, "It is a truly disruptive technology that could change how we do everything."

The D-Wave computer is a product of Canadian startup D-Wave systems. The company claims that it is the first commercially available quantum computer. The computer operates by using a superconducting chip called a quantum annealer.

Despite its impressive features and possibilities, D-Wave chips are controversial among quantum physicists. Experts on the matter are somewhat skeptical whether quantum computers can beat out conventional computers.

Google claims that the company's latest research paper has proof that quantum computers can indeed beat conventional computers. The company created a series of races between conventional computers with a single processor against the D-Wave computer installed at NASA.

Google Quantum AI Lab leader Hartmut Neven said in a statement, "For a specific, carefully crafted proof-of-concept problem we achieve a 100-million-fold speed-up."

Neven said that the research paper has yet to be reviewed by experts. He added that research will be published in scientific publications within the next couple of weeks, according to Technology Review.
