... together. Thus the state space is 2n-dimensional. Now in contrast to a classical system, which can be completely defined by describing the state of each individual component, in a quantum system, the state cannot always be described by considering only the component pieces. ...

... SO(3) and SU (2) are not isomorphic, but they are “locally isomorphic”, meaning that as long as we consider only small rotations, we can’t detect any difference. However, a rotation of 360◦ corresponds to a element of SU (2) that is not the identity. Technically, SU (2) is a double cover of SO(3). As ...
