光纤通信改变了人们感知信的方式,人们可以充分利用网络取或者交换信息。在量子领域,纤内传输的单光子就是一种几乎想的量子信息载体,它具有自由多(包括极化、空间、相位和振等)、易探测、传输速度快、距长、损耗低等优点。科学家们正力于发展量子信息网络中的各类术以便实现远距离加密传输、分式量子计算以及量子感知等。为实现这些远大目标,人们需要克服
Fiber-optic communication has changed the way people perceive letters, and people can take full advantage of the network to take or exchange information. In the field of quantum, the single photon transmitted in the fiber is an almost ideal quantum information carrier, which has more freedom (including polarization, space, phase and vibration), easy to detect, fast transmission, long distance, low loss advantage. Scientists are working on the development of various types of quantum information network in order to achieve long-distance encrypted transmission, fractional quantum computing and quantum perception. People need to overcome these ambitious goals
