量子科学实验卫星的发射是一件重要的事情,对建立全球性的通信网络,构建“量子互联网”至关重要。量子通信的好处在于保密性强、安全性高。在量子通信网络下,如果有人设法窃取你的私人通讯,你会立刻察觉到,这样就可以启动相应的措施保护个人的隐私和安全。而在现有的通信技术手段下,这是无法做到的。在量子物理中,一些尺度下的现象必须要通过量子力学来描述。比如,精准发射导弹可以用经典力学进行描述,但是到了微观层次自然就成了量子力学。要 The launch of a quantum science experiment satellite is an important event that is crucial to establishing a global communications network and building a “quantum Internet”. The benefits of quantum communication lie in the high degree of confidentiality and security. In the quantum communications network, if someone tries to steal your personal communications, you immediately notice that this will enable you to initiate appropriate measures to protect your privacy and security. In the existing means of communication technology, this can not be done. In quantum physics, phenomena at some scales must be described by quantum mechanics. For example, precision launch missiles can be described by classical mechanics, but by the micro level they naturally become quantum mechanics. want
