Red-Green-Blue multi-channel quantum representation of digital images

A new quantum multi-channel Red-Green-Blue (RGB) representation for digital images including the preparation and retrieving procedure is proposed. In our method, the images are represented by using two entangled qubit sequences where the first sequence are employed to encode the RGB color information of the pixel and the second one denotes the position of it. The potential applications of the proposed representation, which introduces some useful quantum image processing operators is discussed and supported by software simulations.
