In some calculations we need to find arrangement of items(like atoms in a molecule). As the number of items grows, the number of possible arrangements grows exponentially. For finding the best arrangement, digital computers iterate through each permutation and then identify which does best at achieving the goal. In many cases this can require an enormous number of calculations.
Same is the case for enhancing cyber security by trying out different combinations of passwords.
The multiplicity of states through superposition in quantum computers allows faster and cheaper calculations.
Nice article, What type of calculations can present Quantum Computers do ? Any examples?
