Coherent state is one thing and decoherence is something else. The coherent state has the form $ (\text I) \ |\alpha \rangle = e^{-\alpha ^2/2} \sum _n \frac {\alpha ^n}{\sqrt {n!}} |n \rangle.$ where $|n \rangle$ is a Fock state of n identical particles. This state is a coherent superposition of Fock states, and its density matrix has diagonal and ...
