Willow: Has Google cracked a key challenge in quantum computing?

From the show

In this Science segment, we take a closer look at Google's announcement that it has cracked a key challenge in quantum computing, with a new chip capable of almost unfathomable speeds. Dubbed Willow, the chip performed a standard test in under five minutes, whereas today's fastest supercomputers would have taken billions of years. So what exactly is the quantum revolution and what is it set to change in our world? FRANCE 24's Julia Sieger tells us more.
