英文摘要：

Quantum information processing with continuous variables is an important part in quantum in- formation science. Quantum information processing with continuous variables based on quantum state of optical field complete the transmission and processing of information by using quantum state of optical field as quantum resource and combining all methods of quantum manipulation for optical field. In this short review, we briefly introduce the concept, preparation and manipulation methods for optical quantum state which plays important roles for quantum information pro- cessing with continuous variables. The research progress and development tendency in quantum communication, quantum computation and quantum error correction with continuous variables are also presented.
