量子通信是事关国家信息和国防安全的战略性领域,且有可能改变未来信息产业的发展格局,因此,其不可避免地成为世界主要发达国家及地区优先发展的信息科技和产业高地美国:列入国家战略实现系列突破在美国,对量子通信的理论和实验研完开始得较早,并最先被列入到国家战略、国防和安全的研发计划。上世纪末,美国政府便将量子信息列为“保持国家竞争力”计划的重点支持课题。而隶属于政府的美国国家标准与技术研究所(NIST)则将量子信息作为三个重点研究方向之一。随后,美国加 Quantum communication is a strategic area that relates to national information and national defense security and may change the future development of the information industry. Therefore, it will inevitably become the priority area of ​​information technology and industry in the major developed countries and regions in the United States: A series of breakthroughs in the implementation of the national strategy In the United States, the theory and experiment on quantum communication started earlier and were first included in the national strategy, national defense and safety research and development programs. At the end of the last century, the U.S. government listed quantum information as a key support issue for its plan to “maintain its national competitiveness.” The National Institute of Standards and Technology (NIST), part of the government, uses quantum information as one of its three key research areas. Subsequently, the United States plus
