摘要
“上帝说要有光，于是就有了光”。光与人类的生活息息相关．却令人感到既熟悉又神秘。“光到底是什么”？人类自从有意识之日起，就一直在思考和探索这个问题。经过上千年的思索，人们基本上有了结论．光既是粒子也是波。具有波粒二重属性。但这是人们在经典世界观察光得到的结论。笔者最新的实验结果表明，光不仅仅是以粒子或者波的状态存在这么简单，还存在用经典世界的语言无法描述的量子状态，究竟能看到什么取决人们选择哪种角度去观察它。这个发现使得人们对于“光是什么？”这个问题有了新的见解。
The history of understanding light, one of the most familiar and fantastical things around us, is reviewed. On this basis of Bohr’s complementarity, light can be in the quantum superposition of wave and particle by using a quantum detector for single photon, which differs from the previous opinion. Light is actually both wave and particle, and also neither wave nor particle. Our result provides the full view angle for people to understand the nature of light and a whole new understanding of Bohr’s complementarity.
