Realtime Control Latency Consolidation

Timestamp: 2026-05-22T00:13:57.520930+00:00

Claim Boundary

• Local lane: host-only no-QPU control loop latency (Python vs Rust full loop).
• IBM lane: externally visible runtime windows only (submit-to-result); no direct intra-shot hardware feedforward latency claim.

Local Host Loop (ms/tick)

• Python mean: 3.664295 ms, std: 0.959325, n=3
• Rust mean: 0.000136 ms, std: 0.000034, n=3

IBM Runtime (s submit-to-result)

• Feedback dynamic mean: 14.345 s, std: 15.358, n=8
• Control open-loop mean: 12.163 s, std: 11.893, n=8
• Capacity sweep mean: 7.723 s, std: 1.757, n=12

IBM Runtime Rust Orchestrator (s submit-to-done)

• Rust submit-to-done mean: 7.338 s, std: 0.343, n=4
