IBM Heron r3: Layer fidelity (error per layered gate)
3.08 × 10⁻³ error per layered gate
As stated in the source: “EPLG-100 = 0.00308 (x10^-3 in source)”
Caveats
Preprint, not peer reviewed. Benchmark implementations are Metriq's own (metriq-gym) and may differ from vendor definitions. EPLG is an error rate (lower is better), not a layer fidelity; chain selection method not read in full. Measurement window only (Nov 2025 to Feb 2026).
- Set-up
- ibm_boston. Layer-fidelity/EPLG on qubit chains of length 10, 20, 50, 100 where supported; value shown is chain length 100. Data captured November 2025 to February 2026.
- Method
- EPLG (error per layered gate, derived from layer fidelity) at chain length 100, metriq-gym implementation; closest ID is layer-fidelity
- Compared only with
