I had a guy I knew in a PhD in quantum computing and he told me that he was working on making an algorithm to perform edge detection on an image in O(1), apparently it's possible to do some operation much quicker with quantum computing A paper i found on edge detection https://arxiv.org/html/2404.06889v1#:~:text=Quantum%20Hadamard%20Edge%20Detection%20(QHED,mainly%20works%20for%20binary%20images https://arxiv.org/html/2404.06889v1#:~:text=Quantum%20Hadama....
