16 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Compare caller-declared qubit count, connectivity and gate-duration requirements with supplied architecture capability records. No verified best-platform recommendation.
Compare structured benchmark protocol, workload, metric, noise and overhead declarations. Flags mismatches; labels are not independently validated.
Calculate a surface-code resource scenario under an explicitly named layout and supplied error assumptions. For planning; not a demonstrated physical implementation.
Check supplied stabilizer generators for commutation, independence and inconsistent constraints before analysing a code. No logical-error or fault-tolerance guarantee.
Fit a bounded damped Rabi/Ramsey trace by frequency-decay grid search; report residuals, resolution, aliasing refusal and edge hits. No parameter confidence interval.
Fit supplied randomized-benchmarking decay observations with residuals and protocol-bound error estimates. Not a platform-independent quantum-computer ranking.
ChainQuery Bitcoin Intelligence: independent Bitcoin-native on-chain data over x402, no API key. Live mempool fee-pressure signal (state low/moderate/high/severe + score in sat/vB).
Lint up to 128 declared gates on eight qubits for arity, target, angle and post-measurement errors. Returns scheduling depth; no simulation or equivalence proof.
Quantum circuit simulation (Qiskit Aer): statevector, density-matrix (noise), stabilizer, and MPS methods; shots, expectation values, and seeded determinism. Sync tier up to 24 qubits. Paid in USDC on Base or Solana.
Invert a supplied single-qubit readout calibration and report sensitivity and nonphysical corrected fractions without clipping. Calibration uncertainty not estimated.
Compare circuit durations with supplied T1/T2 values using an explicit relaxation/dephasing model. For scenario planning; not a measured device-fidelity guarantee. New modular adapter: retained result recovery for 24 hou...
Calculate squared Uhlmann fidelity and purity for two supplied single-qubit density matrices. Explicit conventions; no experimental certification. New modular adapter: retained result recovery for 24 hours, minimal recei...
Calculate X, Y and Z Pauli expectations for a supplied valid single-qubit density matrix. Returns basis conventions; not a hardware measurement. New modular adapter: retained result recovery for 24 hours, minimal receipt...
Check a supplied single-qubit complex density matrix for unit trace, Hermiticity and positive semidefiniteness with explicit tolerance; no hardware validation. New modular adapter: retained result recovery for 24 hours,...
For agents reviewing shot-count results: return probabilities and binomial confidence intervals with the interval method and independence assumptions. New modular adapter: retained result recovery for 24 hours, minimal r...
Problem: Select a supported execution plan against the supplied cost, depth, duration limits, and weights. Input: JSON with plans, weights, maximum cost usd, maximum depth, maximum duration seconds. Result: ranked feasib...
