Scientists in China say their latest quantum computer has solved an ultra-complicated mathematical problem within a millionth of a second – more than 20 billion years quicker than the world's fastest supercomputer could achieve the same task.

The JiuZhang 3 prototype also smashed the record set by its predecessor in the series, with a one million-fold increase in calculation speed, according to a paper published on Tuesday by the peer-reviewed journal Physical Review Letters.

The research team is led by Pan Jianwei, a leading scientist in China's national quantum research programme, from the University of Science and Technology of China at Hefei, in the eastern province of Anhui.

The first Jiuzhang machine – named after an ancient mathematics textbook – was built by Pan's team in 2020. The series uses photons – tiny particles that travel at the speed of light – as the physical medium for calculations, with each one carrying a qubit, the basic unit of quantum information.
