(Bloomberg) — Alphabet Inc.’s Google said it’s built a computer that’s reached “quantum supremacy,” performing a computation in 200 seconds that would take the fastest supercomputers about 10,000 years.

The results of Google’s tests, which were conducted using a quantum chip it developed in-house, were published Wednesday in the scientific journal Nature.

“This achievement is the result of years of research and the dedication of many people,” Google engineering director Hartmut Neven said in a blog post. “It’s also the beginning of a new journey: figuring out how to put this technology to work. We’re working with the research community and have open-sourced tools to enable others to work alongside us to identify new applications.”

The idea behind quantum computing is to exponentially improve the processing speed and power of computers to be able to simulate large systems, driving advances in physics, chemistry and other fields. Rather than storing information in binary 0s or 1s like classical computers, quantum computers rely on “qubits”, which can be both 0 and 1 simultaneously, dramatically increasing the amount of information that can be encoded.
