In August 2012, a groundbreaking achievement in quantum science was reported by Chinese scientists, led by Pan Jianwei. They successfully demonstrated the first free-space quantum teleportation and entanglement distribution, marking a major milestone in the development of quantum communication technology. This breakthrough laid the foundation for the world's first "quantum communication satellite," which later became a key project under the Chinese Academy of Sciences. The research was published in *Nature*, one of the most respected scientific journals globally, highlighting the significance of quantum information as a secure and efficient method of data transmission. With its unparalleled security, quantum communication is seen as a critical component of future information technology, driving global research in physics and technology.
By 2014, China had made remarkable progress in this field. News broadcasts highlighted the rapid advancement of quantum communication technology, with Pan Jianwei leading efforts to build the world’s first quantum communication backbone. Unlike traditional communication methods, quantum systems ensure that any interception of data will be immediately detected. A 2,000-kilometer quantum-secured network stretching from Beijing to Shanghai was being constructed, with applications ranging from government communications to financial systems. In an era of growing cyber threats, quantum communication holds strategic importance for national security.
As the technology advanced, several companies emerged as key players in the quantum communication sector. For example, Zhejiang Dongfang partnered with Pan Jianwei’s team to establish a joint venture focused on quantum network technology in Zhejiang. Huagong Science and Technology developed quantum dot lasers essential for quantum communication systems. Shenzhou Information, a subsidiary of Digital China, contributed to the construction of secure information systems across various industries.
Other notable companies included Sanlux, which engaged in military-civilian technology collaboration, and Fujing Technology, which specialized in optical crystals used in laser and communication systems. 3D Communication provided wireless coverage solutions, while CITIC Guoan expanded its presence in the information industry. Yanneng Power focused on new energy projects, and Han Cable Co., Ltd. produced high-tech cabling solutions for power and communication infrastructure.
Variety Shares expanded its reach in the lottery technology sector, and Zhongtian Technology diversified into photovoltaic backplanes and submarine cables. Yongding Co., Ltd. remained a leader in communication cables, supplying products to both domestic and international markets.
These developments reflect the growing interest and investment in quantum communication, signaling a new era in secure data transmission and technological innovation.
