Google unveils quantum computing chip

Google has unveiled a new chip that it claims takes five minutes to solve a problem that would currently take the world's fastest supercomputers ten septillions, or 10,000,000,000,000,000,000,000,000 years to complete.

The chip is the latest development in a field known as quantum computing, which is trying to use the principles of particle physics to create an incredibly powerful new type of computer.

Google says its new quantum chip, called Willow, includes key "advances" and "paves the way to a useful, large-scale quantum computer."

However, experts say Willow is, for now, a largely experimental device, meaning a quantum computer powerful enough to solve a wide range of real-world problems is still years and billions of dollars away.

The quantum problem

Quantum computers work in a completely different way than the computer on your phone or laptop.

They use quantum mechanics, the strange behavior of ultra-small particles, to solve problems much faster than traditional computers.

It is hoped that quantum computers may be able to use that ability to speed up many complex processes, such as creating new drugs.

There are also fears that it could be used for disease, for example to break certain types of encryption used to protect sensitive data.

In February, Apple announced that the encryption that protects iMessage conversations is being made "quantum proof" to stop them from being read by future powerful quantum computers.

Hartmut Neven runs Google's Quantum AI lab that created Willow and describes himself as the project's "chief optimist."

He told the BBC that Willow will be used in some practical applications but declined, at the moment, to give more details.

But a chip capable of running commercial applications won't appear before the end of the decade, he said.

Initially these applications would be the simulation of systems where quantum effects are important./ CNA
