Coherent states and the reconstruction of pure spin states
... reconstruction of both pure and mixed spin states, can be found in [14]. Inspired by tomographic methods to reconstruct the density matrix of a particle, an entirely different approach was worked out in [15], and it has been adapted in [16] to determine a single quantized cavity mode. Coherent state ...

Then, there is a dichotomy in quantum mechanics today: On the one hand, people realize that all particles have wave properties that behave like photons of light. On the other hand, the current theories of quant ...
