Because it's a typo. China spend $101 Billion on all research in 2015. A small portion of that was more quantum physics.

WSJ issued a correction, as noted in a different comment in the thread.

Thank for the correction - that number seemed unreasonably large.

That's because it's a fraudulent number with zero supporting evidence. There's no actual public data on what China is spending on "quantum physics."

$100 billion in 2015 would be more than all venture capital in the entire country that year. It'd be equal to 70% of all of their claimed military spending for that year.

That's what they do; Ask any economist or financial analyst.

Not only are the numbers fluffed up, there is zero transparency on what exactly the figure represents, what the progress made was, what the outcomes were - all to please their "benevolent" dictator
