Machines that manipulate qubits, quantum computer, can do things that are impossible for a classical computer. Quantum computers are, theoretically, more powerful than classical computers could ever possibly be. Build a sufficiently large one and you can crack all the ciphers on the Internet; as a little game, you could listen in to any "secure" online transaction, crack the code and steal the credit-card numbers and personnal information that have been exchanged—something that is beyond the ken of the best supercomputers in the world.

Yes, but can it tell whether this boy is cute or not?

De toute façon, on finira poar trouver des problèmes qui sont aux versions quantiques des algoritjmes ce que sont les problèmes NP-complets aux versions classiques. Ptêt bien d'dire si s'tigo lo frait point bander l'moine !
