Google unveils ‘mindboggling’ quantum computing chip

Chip takes minutes to complete tasks that would otherwise take 10,000,000,000,000,000,000,000,000 years

It measures just 4cm squared but it possesses almost inconceivable speed.

Google has built a computing chip that takes just five minutes to complete tasks that would take 10,000,000,000,000,000,000,000,000 years for some of the world's fastest conventional computers to complete.
