Thinking Inside The Box: some experimental measurements in
... Any pure state of a spin-1/2 (or a photon) can be represented as a point on the surface of the sphere – it is parametrized by a single amplitude and a single relative phase. This is the same as the description of a classical spin, or the polarisation (Stokes parameters) of a classical light field. O ...
