Bounded definition
A boundary between estimator-bias reduction on noisy circuits and encoded fault detection and correction.
What the cited work establishes
The paper presents zero-noise extrapolation and quasiprobability error-cancellation schemes for expectation estimates in short-depth noisy circuits.
The models, apparatus, protocols, datasets, and comparisons reported in Error Mitigation for Short-Depth Quantum Circuits.
Claims: urn:maha:claim:error-mitigation-versus-correction
What remains a separate question
Reduced estimator bias must not be relabeled as a logical error rate or fault-tolerance demonstration.
Mitigation reduces bias under assumptions and sampling overhead; it does not encode and correct arbitrary faults or guarantee scalable computation.
Connected domain graph
Typed dependencies preserve publication state.
Only independently canonical records receive public links and relation statements. Draft graph topology remains private.
Quantum error mitigation
inbound connection · method
Mitigation and correction differ in mechanism, resources, and guarantees.
Quantum error mitigation
outbound connection · method
Mitigation supplies the estimator-focused side of the comparison.
Quantum error correction
outbound connection · method
Correction uses encoded redundancy and syndrome processing rather than only estimator reconstruction.
Claim ledger
Every proposition keeps its own evidence state.
The cited mitigation constructions operate without additional encoded qubit resources and target expectation-value bias in short-depth circuits.
- Scope
- The models, apparatus, protocols, datasets, and comparisons reported in Error Mitigation for Short-Depth Quantum Circuits.
- Boundary
- Reduced estimator bias must not be relabeled as a logical error rate or fault-tolerance demonstration.
- Uncertainty
- No platform-independent uncertainty interval exists; numerical values remain attached to the source experiment or model and its stated assumptions.
- Replication
- This candidate records one bounded source package. Independent replications and contradictory measurements must be compiled as separate records before maturity is upgraded.
