Grover’s algorithm is often misunderstood as a tool that evaluates all possibilities simultaneously; instead, it provides a square-root speedup for specific search problems, offering a limited but meaningful improvement over classical methods. The video explains how Grover’s algorithm manipulates quantum states geometrically and clears up common misconceptions about quantum speedups.
