The state of the nuclear spin (up or down, or superposition) is definitely something that has been proposed as a quantum bit ("q-bit"), and many quantum computer proposals have used the nuclear spin as their proposed q-bit. The tricky thing is that these nuclear spins are all interacting with each other, and exercising control of the full state in the presence of those interactions is very tricky.
