Quantum reservoir computing (QRC) is a promising paradigm for utilizing near-term quantum devices in temporal machine learning tasks.
A study investigates a minimal model of a driven-dissipative quantum reservoir consisting of two coupled Kerr-nonlinear oscillators.
Using Partial Information Decomposition (PID), the researchers analyze how different dynamical regimes encode input drive signals.
The results reveal a transition from redundant to synergistic encoding near a critical point, with synergy enhancing short-term responsiveness and dissipation supporting long-term memory retention.
