I've found online that the coherent state of the harmonic oscillator is
|\alpha \rangle = c \sum_{n=0}^\infty \frac{\alpha^n}{\sqrt{n!}} | n\rangle
where
|n\rangle = \frac{(a^\dagger)^n}{\sqrt{n!}} |0\rangle
and |0> is called the initial state.
I've some code where I need to have this initial state for j=4, so it should be a 9 by 1 vector right?
How is this initial state found?
