摘 要：Non-classical states of light,which include squeezed and entangled states of light,are the cornerstone of quantum mechanics and quantum information *** date,non-classical states of light with much higher quality than before are required to develop high-fidelity quantum information processing and high-precision quantum *** and entangled states with approximately 10 dB noise below the corresponding shot noise limit have been generated using a series of methods,which means that the noise variance reaches a few percent of the vacuum *** teleportation,which means transferring an unknown quantum state from a sending station to a distant receiving station supported by entangled states,is the foundation of quantum computation and quantum communication *** teleportation in continuous variable regions is unconditional because the entangled states used are always *** quantum teleportation distance was recently extended to the order of kilometers,which paves the way for constructing a practical quantum information network.
