Hong Kong's "South China Morning Post" website on January 14 published a report entitled "Why China Is Selling" Quantum Underwear ", claiming that China's online stores are currently full of products claiming to have the advantages of quantum technology. Technology is almost irrelevant. You can buy socks with quantum technology, quantum underwear or some quantum alcoholic beverages. However, this is not the first time that technical buzzwords have entered an ambiguous field. The most striking example is the blockchain technology boom. Although the impulse to impose the term blockchain on anything has faded, academics are still developing blockchain technology.
