Scheme of the chip in a perpendicular plane showing the input output connections and the parameters of the simulation. Here β is the propagation constant, q is the vertical coupling constant, κ is the horizontal coupling constant and d the diagonal coupling constant. (a) The scheme in which each plane is associated with a component of the qubit simulates Eq. (3). (b) The crossed links allow for a stronger temporal mixing of the qubit components in the derivative. This situation corresponds to the second example of Eq. (3).
