Logplot of superposition of |B=3> and |B=-3> coherent states

50 Fock states

100 Fock states

100 Fock states on a log scale (you can see weird interference patterns here)...

epsilon=1.2

epsilon=4. Note that the color in these color images is scaled to the maximum value of

of the Q distribution in the image, hence "red" in one image does not correspond to the same Q

distribution value as "red" in another image.

Here are the three images again (epsilon=0.2, 1.2, 4), but this time they're properly scaled

relative to one another. It really does seem that the "squeeze" operator seems to

stretch and rarefy the state rather than squeeze it (though I may have screwed something up).

Below are some snapshots showing the time evolution due to the Kerr Hamiltonian:

At t=32, 96, we get what looks like 4 coherent states

At t=64 we get 2 coherent states

At t=128, the state would return back to the original coherent state, |A=4>.

A ~2mb gif of one period of Kerr time evolution is shown here.

Poorly commented MATLAB code which generated all of these pictures is available here.
