GOOGLE says it has developed a quantum computer billions of times faster than any other technology.
The US giant claims it took 200 seconds to carry out a task that would have taken a supercomputer around 10,000 years.
Experts called it a “phenomenally significant” breakthrough.
In conventional computers, a unit of information — or bit — can have a value of 0 or 1.
But quantum bits can be both 0 and 1, allowing multiple computations at once.
University College London expert Dr Ciarán Gilligan-Lee said: “It is the first baby step on a long journey where we can fully harness the power of quantum mechanics that will eclipse anything our current laptops or even supercomputers can do.
“It is a huge technological and scientific milestone.”
The findings were published in the journal Nature.
Dr Luke Fleet, a senior editor at Nature, said quantum machines are still years, if not decades away.
He said: “This breakthrough result marks the dawn of a new type of computing….it allows you to compute things faster – not just a little, but lot faster!
“This is transformative as people will be able to compute things that they previously thought impossible.”
