From: Realising and compressing quantum circuits with quantum reservoir computing
The QN is composed of a randomly connected network of nodes (black circles) driven with coherent excitation P (blue arrow). The qubits on which computation is performed are denoted by qk (k ranges from 1 to the number of qubits). Quantum operations on qubits qk are performed by coupling them through the QN. Jkl (l ranges from 1 to the number of network sites N) represents a control layer of tunnelling amplitudes connecting the qubits to the QN. Different colours of qubits correspond to different levels of optimisation.
