On July 3, Anhui Wentian Quantum Technology Co., Ltd. announced that the first chip-level post-quantum cryptographic card in China, which was conquered by the company and the team of Professor Liu Dongsheng of Huazhong University of Science and Technology, was officially launched, marking a breakthrough in the engineering application process of quantum security technology in my country and laying a solid foundation for future post-quantum cryptographic migration. Dr. Qian Yongjun, an expert in Wentian quantum security systems, introduced that with the rapid development of quantum computing technology, traditional cryptographic systems are facing unprecedented challenges. Once the traditional cryptographic system is cracked by quantum computers, financial transactions, medical data, energy scheduling, command and control systems will face the risk of information leakage. Therefore, post-quantum cryptographic technology designed to resist quantum computer attacks came into being. "Post-quantum cryptographic technology is a mathematical cryptographic system that can be implemented on existing electronic computers and has the ability to resist future quantum computer attacks. It can provide a 'better solution' for information security and is regarded as one of the key technologies for 'controlling information rights.'" Qian Yongjun said.
