摘要：

In order to improve the efficiency of quantum secure direct communication, a controlled quantum secure direct communication protocol based on Huffman compression coding is proposed in this paper. The protocol combines classical Huffman coding with quantum communication, Alice performs Huffman compression code and unitary operation on the secret messages and sends them to Bob, and then Bob obtains the corresponding secret messages through decoding operation. In this protocol, communication efficiency can be effectively improved by using Huffman compression coding and sequence generator. As a result, the longer the secret messages, the higher the communication efficiency.
