Show affiliationsConsider a spin s prepared in a pure state. It is shown that, generically, the moduli of the
spin components along three directions in space determine the state unambiguously. These probabilities are accessible experimentally by means of a standard Stern-Gerlach apparatus. It is therefore possible to reconstruct a generic pure state on the basis of 6s independent measured intensities.
