* Idea: Can start with a _coh in _kin and apply a group averaging procedure to implement the Dirac prescription, or construct a coherent state directly in _phy.

In Quantum Field Theory > s.a. states in quantum field theory; QED; minisuperspace quantum gravity.
* Motivation: Given a classical field, there is no unique quantum state one can associate with it, but the most natural or "likely" one is the coherent state, since it corresponds to the state of a quantum field after a classical source has been turned on for some time [1.02.85, from a meeting with Rafael].
* Interpretation: The probability of finding n quanta in the state _z is a Poisson distribution with mean z z*.
