Query: A Quantum Edge Detection Algorithm   The application of quantum computing to the field of image processing has
produced several promising applications: quantum image representation
techniques have been developed showing how, by taking advantage of quantum
properties like entanglement and superposition, many image processing
algorithms could have an exponential speed-up in comparison to their
"classical" counterparts. In this paper, after briefly discussing some of the
main quantum image representation methods, we propose an improved version of a
quantum edge detection algorithm.
