Abstract: How to subtly embed secret information in carriers (text, image, audio) has been a challenge for researchers. From the perspective of quantum information, a new idea of information hiding is proposed to construct quantum entangled states to realize the hiding and transmission of secret information without destroying the carrier data in this paper. In order to increase the transmission capacity of secret information, the quantum secret information compressed by Schur transform is encoded into the phase of the entangled state for transmission. During the bit transmission, the new protocol can securely and covertly send secret quantum bit information. The receiver can extract the secret information and obtain a lossless quantum image by using the quantum Fourier transform (QFT) and the measurement results of the received quantum state. In addition, a specific method is given to extract the secret quantum state information and then convert the quantum bits to classical bits, which can effectively increase the capacity of secret information transmission. This scheme ensures the security of the secret information transmission without sacrificing the carrier image quality.
