英文摘要： Quantum computer is an inevitable stage in the development process of computer. Quantum information, especially quantum media information, will have important researching value in the era of quantum computer. Security for quantum images is a key issue that cannot be evaded in quantum media processing technology. Taking the encryption security of quantum images as the applied background, this project studies the method of quantum image with low preparation complexity and high applicability. Based on it, the project designs quantum image processing algorithms which service quantum image encryption. Selective encryption for quantum images and polynomial and visual cryptography based quantum image secret sharing will be further researched. Moreover, the project will establish the evaluation index system for quantum image encryption algorithm to provide the evaluation criterion for the future study of encryption schemes. The project focuses on the key issues about the quantum image representation with low circuit designing complexity and high applicability, the halftone of quantum color image, the logic operation of quantum state and the noise superposition of quantum image. The research establishes the foundation for quantum media processing technology.
