Hello and welcome to Business Daily from the BBC with me, Manuela Sanagossa.

In this edition, computers that might solve climate change and discover new cures for cancer,

say hello to the world of quantum computing.

This is in its early stages, but the hope is that many of these problems will see an acceleration from the

computing power that these small-quem devices bring to the table. Google says it's made a big

breakthrough, but not everyone's convinced. There's an awful lot of promise that people are

arguing about whether that promise is going to have real world impacts soon or a long way away,

and how big those real world impacts will be.

That's all here in Business Daily from the BBC.

The tantalizing promise of quantum computers is that they can do certain tasks exponentially faster than classical machines.

And the quantum supremacy experiment is proof that this is indeed the case.

Google's video there announcing its achieved quantum supremacy.

A big deal, the company said, because quantum computing is another one of

those tech revolutions that could change the world. The trouble is you need a PhD in physics to

really understand what it is and how it works. Enthusiasts believe quantum computing could solve

many of humanity's most intractable problems.

We'll be discussing its potential in just a moment.

First, though, over to the BBC's technology correspondent Rory Ketland-Jones.

Was the Google breakthrough as big a deal as it said?

Well, what they're claiming is something called quantum supremacy,

which is where a quantum computer beats a standard computer, a supercomputer, at some particular task.

And this had been expected for a long time, but it hadn't been expected to happen quite so soon.
