Are quantum mechanics still complicated? Certainly. If the discovery holds up, though, it could take a some of the mystery out of what has previously been an arcane system. The long term impact is hard to nail down, but the university believes that it could lead to new approaches to quantum cryptography. If you see a sudden rise in ultra-secure internet communications, you'll know who to thank.
