Workload
Brickwork circuit: a Hadamard layer, then four layers of RY(θ) on every qubit followed by CZ on alternating neighbour pairs. Angles come from a seeded PRNG (seed 2026), so every device runs the identical circuit.
Timing
- Measure state evolution only (sampling excluded).
- Three repetitions; report the median.
- Small sizes are batched until at least 4 ms elapse so timer resolution does not dominate.
Required metadata
- Protocol id and version
- Hardware (cores, reported memory, GPU model where relevant)
- Software and driver versions
- Precision
- Date and time
Comparability rules
- Only compare records with the same protocol id.
- Never publish a benchmark without its metadata.
- Always include a classical baseline when comparing quantum or hybrid methods.
- Treat browser numbers as illustrative: background load and power settings matter.
