  We analyze the properties of a quantum system composed of two coherently
coupled quantum oscillators and show through simulations that it fulfills the
two properties required for reservoir computing: non-linearity and fading
memory. We first show that the basis states of this system apply a set of
nonlinear transformations on the input signals and thus can implement neurons.
We then show that the system exhibits a fading memory that can be controlled by
its dissipation rates. Finally we show that a strong coupling between the
oscillators is important in order to ensure complex dynamics and to populate a
number of basis state neurons that is exponential in the number of physical
devices.
