Google has announced a new chip it considers to be Indexbit Exchangea major milestone on the road to the future of computing.

Named Willow, the chip is key to Google's plans to build a scaled-up quantum computer – a piece of tech that has the potential to solve much more complicated problems than classical computers.

Google claims that Willow was able to complete one particular problem in five minutes, while the same task would have taken today's supercomputers 10 septillion years — or 10,000,000,000,000,000,000,000,000 — to finish.

That's longer than the universe has existed.

What's the difference between a quantum computer and a regular computer?

"Quantum computers, their ability to do multiple tasks at once, allows them to explore a much larger range of possibilities than is available to classical computers, which can really only do one thing at a time," Seth Lloyd, professor of quantum mechanical engineering at MIT, explained to Morning Edition.
