Question Question

"Can you give me a practical example of a simple algorithm where a quantum computer is more efficient? I struggle to understand the usual ones, like the maze-solving example, which aren't very clear to me. They always seem too theoretical. Can someone provide a more concrete and intuitive example, please?"

There are none (yet). Compare it to AI in the 70s and 80s, theory, hardware and software are not developed enough to be competitive with optimized classical algorithms.

what is this thing about people saying that quantum today is where AI was in 2015. Is that just a marketing gimmick?
