Abstract:

The research status of quantum communication at home and abroad is discussed.The problem of quantum non-locality and quantum communication complexity is studied.The GHZ problem is solved by entangled particles,and the minimum number of transmitted bits is discussed by using distributed algorithm.The relationship between non-locality and communication complexity is analyzed,and then the simultaneous message passing model is studied.The results show that compared with the classical communication,the quantum communication efficiency is high,and the quantum non-locality problem and the quantum communication complexity problem can be mutually converted.

Key words: quantum communication, quantum computation, entangled particle, communication complexity, quantum non-locality
