Quantum image
[1] Quantum image is 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.Currently, visual information like images and videos constitutes the largest part of data traffic in the internet.[3] The laws of quantum mechanics allow one to reduce the required resources for some tasks by many orders of magnitude if the image data are encoded in the quantum state of a suitable physical system.[4] The researchers discuss a suitable method for encoding image data, and develop a new quantum algorithm that can detect boundaries among parts of an image with a single logical operation.It contributes a substantial progress towards both theoretical and experimental quantum computing for image processing, it will stimulate future studies in the field of quantum information processing of visual data.
