Quantum reservoir computing with repeated measurements on superconducting devices
A preprint on arXiv proposes a quantum reservoir computing scheme for superconducting devices in which the system is measured repeatedly during its natural dissipative dynamics, and the resulting measurement record is used as a feature stream for time-series prediction. The abstract frames the approach as using the nonlinear and memory properties of quantum dynamics rather than conventional digital quantum circuits. No experimental results are reported in the abstract.

This could make existing cloud-accessible superconducting processors usable as small-scale temporal machine learning testbeds within two years.
The scheme relies on native dissipative qubit dynamics and repeated measurements, which avoids long gate sequences and maps onto current noisy hardware; if readout fidelity and measurement overhead are manageable, experimental comparisons on small time-series tasks could follow without fault tolerance.
