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.

That is analogous to using quantum computing to crack RSA cyphers. The quantum computer produces a solution corresponding to every one of the 2¹⁰²⁴ or however many possible keys. Then you only have to read every one to work out which is the correct decryption

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
