, and ∆p c = ℏωc 2 . In the phase space representation, this can be intuitively visualized as in Fig. , where the X 1 = 2ω c /ℏq c and X 2 = 2/ℏω c p values within one standard deviation of the expectation values are represented by the shaded circle. This shows how coherent states equally distribute the x-p uncertainty across x and p.
