Quantum computers don't and won't meaningfully exist for a while, and once they do exist, they still won't be able to crack it. Quantum computers aren't this magical "the end is nigh" gotcha to everything and unless you're that deep into the subject, the bigger question you've got to ask yourself is why is a magic future technology so important to you that you just had to post your comment?

Anyway, back to the subject at hand; here's Apple on that subject:
