Physicists in China challenge Google’s ‘quantum advantage’ - DNA Zone

The numbers in this report are absolutely mind-blowing. 

"Pan and colleagues could find solutions to the boson-sampling problem in 200 seconds. They estimate these would take 2.5 billion years to calculate on China’s TaihuLight supercomputer — a quantum advantage of around 1014."
