量子科学实验卫星项目的正式立项,既意味着中国科学家向完全自主研发世界首颗量子科学实验卫星发起挑战,更意味着中国或将先于欧美拥有量子通信覆盖全球的能力。伴随着互联网的飞速发展,信息安全已经成为人们关心的首选网络问题。而“棱镜门”之后,通信安全与通信保密的重要性更是引发各国政府以及广大公众的普遍关注。人们不安地试图寻找一个答案:究竟有没有一种通信手段是绝对可以信赖的?答案是肯定的。在保密通信领域,量子通信是迄今为止唯一被严格证明“无条件安全”的通信方式。通过量子通信,人们可以从根本上解决国防、金融、政务、商业 The formal establishment of the Quantum Science Experimental Satellite Project means that Chinese scientists are challenged to completely independently develop the world’s first quantum science experimental satellite and meanwhile China will probably have the ability to own global coverage of quantum communications before the United States and Europe. With the rapid development of the Internet, information security has become the preferred network issue that people care about. And “Prism Gate ”, the importance of communication security and communication confidentiality is even caused the widespread concern of governments and the general public. People are unequivocally trying to find an answer: Is there any absolute trust in the means of communication? The answer is yes. In the field of confidential communications, quantum communication is by far the only strictly “unconditional security” communication method. Through quantum communications, people can fundamentally solve national defense, finance, government affairs and commerce
