英文摘要： Exploiting the promises that quantum computation and quantum information offers to us, the production and encryption of multi-channel quantum video is proposed. The color information on RGB channels of the quantum video is stored concurrently by utilizing many fewer qubits and the quantum video could be retrieved in classical domain by means of the quantum measurement on ancilla qubits. In addition, the quantum information key is dynamically generated by applying the quantum measurement on the key frames of the quantum video so that the color information and geometric information in the quantum video could be transformed, which ensures the realization of a secure, fast, and flexible encryption to multi-channel quantum video. Another contribution in this study is establishing a simulation system to simulate the representation and retrieval of multi-channel quantum video, the dynamic generation and compression storage of quantum information key, and the encryption and decryption of quantum video. The study will open the door towards color quantum video processing and significantly contribute to the video processing and secure communication on quantum computers.
