Representations of Lorentz and Poincaré groups
... 4 · (4 − 1)/2 = 6 independent3 generators (corresponding to the 3 rotations and 3 boosts) so that the adjoint representation of the Lorentz group is six-dimensional. In other words, we could write the Lie algebra as [J˜a , J˜b ] = if ab c J˜c where a, b, c = 1, . . . , 6, by defining (J˜1 , J˜2 , J˜ ...

... regime must be something completely different than its classical analogue. In the quantum mechanical case the term “intrinsic angular momentum” is often used instead of spin to avoid confusion with classical examples such as the earth. In the Stern-Gerlach experiment a beam of silver atoms is direct ...

In other words, at all times of the computation the machine is in a valid probability distribution of configurations. The quantum model is also a probabilistic m ...
