英文摘要	Processing of digital images is continuously gaining in volume and relevance, with concomitant demands on data storage, transmission, and processing power. Encoding the image information in quantum-mechanical systems instead of classical ones and replacing classical with quantum information processing may alleviate some of these challenges. By encoding and processing the image information in quantum-mechanical systems, we here demonstrate the framework of quantum image processing, where a pure quantum state encodes the image information: we encode the pixel values in the probability amplitudes and the pixel positions in the computational basis states. Our quantum image representation reduces the required number of qubits compared to existing implementations, and we present image processing algorithms that provide exponential speed-up over their classical counterparts. For the commonly used task of detecting the edge of an image, we propose and implement a quantum algorithm that completes the task with only one single-qubit operation, independent of the size of the image. This demonstrates the potential of quantum image processing for highly efficient image and video processing in the big data era.; National Key Basic Research Program of China [2013CB921800, 2014CB848700]; National Science Fund for Distinguished Young Scholars of China [11425523]; National Natural Science Foundation of China [11375167, 11227901]; Strategic Priority Research Program of the CAS [XDB01030400]; Key Research Program of Frontier Sciences of the CAS [QYZDY-SSW-SLH004]; Deutsche Forschungsgemeinschaft [Su 192/24-1]; Qatar National Research Fund (QNRF) under the NPRP Project [7-210-1-032]; Natural Science Foundation of Guangdong Province [2014A030310038]; SCI(E); ARTICLE; 3; 7
