Classical logic, if you want to call it that, is traditionally interpreted as Boolean logic. You have bits of information. They are on or off, yes or no, zero or one. Quantum information deals with the manipulation of qubits. Qubits are little vectors in two-dimensional complex Hilbert spaces. And you can do a little math and show that's equivalent to being a point on a sphere.
