 # Let's consider the "X" state can only have two possible states, cross and bar which are represented by the angle applied, (0 -> 0, bar) and (1 -> $\pi$, cross).
 #
 # If we have a fock state `[[1], [0], [0]]` inputted onto the switch lattice, we want it to route out the photon accordingly at the bottom mode index 2, third waveguide. Accordingly, the top-most switch needs to cross and the bottom most needs to bar in order to achieve this function.
 #

+
 # We can try a little analytical simulator accordingly. Each "switch" state gets replaced by a 2x2 transmission matrix for each specific state, and concatenated to build the corresponding state of the system.
