Five Neutral Atoms Held a Fading Memory
Controlled dissipation let a quantum reservoir process nonlinear time-series signals without an external buffer.
Summary
Controlled dissipation let a quantum reservoir process nonlinear time-series signals without an external buffer.
Simulations of neutral-atom quantum reservoirs found that controlled dissipation was necessary for fading memory, separability and the echo-state property. Performance peaked near the edge of quantum chaos, and the resulting setup solved the nonlinear Mackey-Glass task with as few as five atoms. The paper establishes a theoretical and simulated design regime for near-term devices; it does not report a physical neutral-atom processor running the workload.
