IQM Garnet
IQM superconducting QPU accessed via AWS Braket (eu-north-1). Weekly runs on Wednesdays at 10:30 UTC.
Consistency over time
Within-run consistency score (1 - std dev) — the primary stability metric. Higher is more consistent. Faded line and dots are individual runs; bold line and larger dots are the 4-run rolling average.
Success probability over time
Success probability for a given circuit is the fraction of shots that produced the correct output — where "correct" is the deterministic, noise-free answer computed by classical simulation. Each point is the mean across the circuits sampled that run. The bold line is the 4-run rolling average; faded line and dots are individual runs. The shaded band shows ±1 standard deviation within the run.
Performance breakdown
How success probability varies across circuit depth and input state, aggregated across all runs.
Success probability by circuit depth and input state
Each point is one (depth, input state) combination. Point size reflects how many circuits were run with that combination. Drag to rotate.
Distribution by circuit depth
Mean success by circuit depth
Mean success probability for each depth, averaged across all runs. A declining trend confirms that noise accumulates as circuit depth increases.
Mean success by input state
Does the initial qubit state affect results? Ideally it shouldn't — deviations suggest state-preparation or readout asymmetry.
