Because Xue Qikun and his team made the anti-quantum Hall effect, which is a very heavy quantum reaction in physical science. Those who studied it before won the Nobel Prize after making further research results.
Xue Qikun's research is a major breakthrough in the field of physics research so far, which has great scientific research and commercial value, so it should also be within the scope of the Nobel Prize in Physics.
The Nobel Prize was founded with part of the legacy of Alfred bernhard Nobel, a famous Swedish chemist and inventor of nitroglycerin explosives. Nobel prizes include gold medals, certificates and bonus checks.
