Dicke-state preparation by collision-model circuits: a noiseless budget-fidelity frontier, its circuit cost, and measured fidelities on IQM Emerald

Abstract

Measured Dicke-state fidelities for collision-model preparation circuits on the IQM Emerald superconducting processor, with raw per-circuit outcome histograms, the device calibration snapshot used, and the analysis code needed to regenerate every processed result.
