Quantum computers are not like classical computers. I don't mean that in the sense that quantum computers perform calculations in a different manner, or that they might be faster, or more clever. No, I mean that quantum computers come with a whole set of issues (read: headache-inducing problems) that normal computers don't.

To reduce these problems, researchers have taken to hiding quantum information, albeit not very successfully. It turns out that using more than one type of qubit offers a bit more camouflage to quantum information.
