A Discrete Phase-Space Calculus for Quantum Spins based on a Reconstruction Method using Coherent States
Stefan Weigert
To reconstruct a mixed or pure quantum state of a spin s is possible through coherent states: its density matrix is fixed by the probabilities to measure the value s along 4s(s+1)…

Coherent States and the Reconstruction of Pure Spin States
Jean-Pierre Amiet, Stefan Weigert
Coherent states provide an appealing method to reconstruct efficiently a pure state of a quantum mechanical spin s. A Stern-Gerlach apparatus is used to measure (4s+1) expectations…
