Sample Efficiency Crisis in Quantum Reservoir Computing: Scaling Analysis on 156-Qubit IBM Hardware and Rigetti Simulation

Daniel Mo Houshmand

An empirical study of the training data needed to turn quantum reservoir measurements into useful predictions.

A versioned preprint, research code and a later hardware-provenance correction are public. The Zenodo deposit predates that correction; use the pinned repository record for corrected hardware attribution.

These results do not establish weather-forecast skill or a general quantum advantage. A registered preprint is not evidence of peer review.

The Zenodo deposit has a registered version. The separate SSRN record has no verified manuscript version; consult the corrected provenance for hardware attribution.

The Fundamental Tension in Topological Quantum Reservoir Computing: Why Unitarity Opposes the Echo State Property

Daniel Mo Houshmand

A theoretical study of the tension between reversible quantum evolution and the fading of a reservoir’s initial state.

The original no-go preprint and revised tension preprint share one Zenodo version lineage. They are versions of the same research record, not independent studies.

The argument depends on the stated dynamics and echo-state assumptions. It is not a blanket prohibition on dissipative or measurement-assisted quantum reservoirs.

Separate SSRN record · SSRN
2026 · Manuscript version unverified

The Zenodo preprints form one version lineage, shown newest first. SSRN is a separate record with no verified manuscript version.

Versions matter. The original no-go and revised tension preprints belong to one Zenodo lineage. The separate SSRN records have a registry year of 2026, with no verified manuscript version. For the scaling study, consult the pinned corrected hardware provenance before comparing archived claims.

Machine Learning’s ‘Amazing’ Ability to Predict Chaos

Natalie Wolchover · Quanta Magazine · 18 April 2018.

An accessible introduction to classical reservoir forecasting and the questions behind the primary Pathak studies above. It is context for the research programme, rather than evidence of a QMikeAI result.
