grover's algorithm

Grover's algorithm is a way to quickly search for something in a large list of items. Let's say you have a giant list of numbers and you want to find out which number is the biggest one. Grover's algorithm helps you get the answer much faster than if you looked through the list one by one. It works by using a special mathematical formula to compare each number in the list with the others and find the one that is the biggest.
