For instance, the value of the $C_6$ and $C_3$ coefficients of the [interaction Hamiltonian](programming.md#22-interaction-hamiltonian) are defined by the device. Notably, the `Device` defines the list of `Channels` that can be used in the computation, which have a direct impact on the Hamiltonian that can be implemented.
