Bounded definition
A comparison contract that fixes the circuit family, compiler, calibration snapshot, acceptance statistic, classical baseline, and uncertainty before ranking systems.
What the cited work establishes
The paper defines quantum volume through random circuits of equal width and depth and reports measurements on specified transmon devices.
The models, apparatus, protocols, datasets, and comparisons reported in Validating quantum computers using randomized model circuits.
Claims: urn:maha:claim:hardware-benchmark-scope
What remains a separate question
No one benchmark is a platform-independent proxy for usefulness, reliability, cost, or fault tolerance.
Quantum volume is one aggregate benchmark and does not establish application advantage, fault tolerance, or equivalence across every architecture and compiler.
Connected domain graph
Typed dependencies preserve publication state.
Only independently canonical records receive public links and relation statements. Draft graph topology remains private.
Trapped-ion QCCD architecture
inbound connection · concept
QCCD performance must be compared using architecture-aware workload and transport metrics.
Silicon and quantum-dot spin qubits
inbound connection · concept
Spin-qubit claims require device- and fabrication-specific comparison contracts.
Randomized benchmarking
inbound connection · method
Benchmark interpretation requires the exact gate set, sequence ensemble, fit, and noise assumptions.
Quantum volume benchmark
inbound connection · measurement
Quantum volume is one bounded benchmark contract among several non-equivalent metrics.
Random-circuit sampling
inbound connection · method
The claim depends on the exact task, fidelity metric, classical baseline, and hardware snapshot.
Quantum volume benchmark
outbound connection · measurement
Quantum volume is one explicit instance of a hardware benchmark contract.
Random-circuit sampling
outbound connection · method
Random-circuit sampling uses a different task and baseline contract.
Claim ledger
Every proposition keeps its own evidence state.
The cited quantum-volume protocol demonstrates that a benchmark is operationally defined by a circuit ensemble, execution rule, statistical acceptance test, and device configuration.
- Scope
- The models, apparatus, protocols, datasets, and comparisons reported in Validating quantum computers using randomized model circuits.
- Boundary
- No one benchmark is a platform-independent proxy for usefulness, reliability, cost, or fault tolerance.
- 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.
