QPC Noise Reduction Add-on

A single resilience capability for Quantum Polycontextural Computing: packaging qpc_resilience, qpc_noise_reducer, and SAR into one IBM-ready layer that submits, protects, recovers, and reports for wide polycontextural desks.

How the three engines connect to QPC

QPC defines polycontextural geometry and architecture metrics on the desk. The Noise Reduction Add-on wraps every IBM job path so those metrics arrive through a stronger, structure-aware pipeline: one product surface, three cooperating engines.

QPC owns architecture · the Add-on owns IBM-wired resilience around every desk job

Engine 1

qpc_resilience

IBM SamplerV2 options, unified mitigate path after fetch, structured archives for decode and ranking.

Engine 2

qpc_noise_reducer

Canonical counts, sparse full-register readout, multi-run aggregation, bridge and graph refinement.

Engine 3

SAR

Desk-intelligent recipes for wide QPC layouts: junctions, bridges, full-register contracts, S4 multi-run.

Capabilities

IBM-ready job path. Heron r2 backends (Kingston, Fez, Marrakesh): submit, fetch, mitigate, package.
Wide-desk support. 156Q+ open-reference widths with sparse full-register readout.
Structure-aware recovery. SAR follows polycontextural geometry: junctions, bridges, and desk contracts.
Multi-run strength. Aggregate independent seeds for stabler architecture statistics.
Dual-channel outputs. Raw architecture channels plus enhanced diagnostic channels from the stack.
Locked defaults. Reusable profiles so every new QPC IBM job lands on the same add-on path.
Desk integration. ADMET Lead Desk and junction-RYY geometry modes with a strong hardware signal.

With the Noise Reduction Add-on and locked ADMET junction_ryy geometry, QPC delivered a raw junction gap of 0.185 on ibm_marrakesh (Stage C2 WOW), with Fez Stage B as supporting evidence on the same geometry. Measurable polycontextural structure on IBM Heron r2, carried by a resilience layer built for QPC.

For teams and products

Own the stack. Methods, defaults, and wiring inside the QPC release.
Faster iteration. New quantum tests plug into one add-on.
Clear product story. One site-facing capability.
Architecture-first. Resilience strengthens the pipeline. Polycontextural design carries the claim. Primary architecture metrics stay on raw counts. Mitigated and SAR channels are diagnostic.

Bottom line: QPC Noise Reduction Add-on = qpc_resilience + qpc_noise_reducer + SAR. Built to submit, protect, recover, and report with the depth QPC architecture demands.
