Scientists have discovered a way to sort an array in O(n) time using a quantum computer. The algorithm of the program is
a) Use a quantum computer to shuffle an unsorted array
b) Check if the array is sorted
c) If not sorted, destroy the universe
By the multi-worlds interpretation of quantum theory, the quantum sorting of the array will create 2^(N-1) universes, out of which one will have the array sorted. All the other universes will destroy themselves.
