Known tools 12

compute_expectation

Given a quantum circuit (2-qubit error rate p, qubit count n, depth d), compute the effective error rate, success probability, and optional surface-code or qLDPC overhead.

Inferred read-only

compute_required_error_rate

Inverse of compute_expectation.

Inferred read-only

compute_fault_tolerant_resources

Given an algorithm stated as (numLogicalQubits, tCount) and a physical error rate (or hardwareId), derive the full surface-code + magic-state-distillation footprint from the general laws of the Litinski lattice-surgery cost model (no per-scenario constants): distillation factory choice, tile layout, required code distance, total physical qubits, and wall-clock time.

Inferred read-only

compare_hardware_scenarios

Run the same circuit against multiple current SOTA hardware entries in one call so an agent can rank platforms without N sequential compute_expectation calls.

Inferred read-only

list_current_quantum_computers

Return the representative-entry table of current SOTA quantum computers (id, hardware type, physical qubit count, 2-qubit error rate).

Inferred read-only

list_hardware_timings

Return per-platform gate-cycle timings (2Q gate time, readout time, in SI seconds) plus the representative device and native 2Q gate name, with source URLs.

Inferred read-only

compute_quantum_volume_rate

Compute the Quantum Volume Rate (QV/second): QVR = V_Q / (log2(V_Q) * t_2Q + t_meas).

Inferred read-only

fit_historic_series

Fit a log-linear trend (ln(value) = slope * year + intercept) to one historic series — fidelity or qubit-count — for one hardware type.

Inferred read-only

list_example_algorithms

Return the curated list of example quantum algorithms with published resource estimates (qubit count, depth/gate count, source paper URL).

Inferred read-only

list_qldpc_codes

Return the catalog of supported qLDPC codes (id, label, family, n, k, d, circuitLevelDistance, ancilla counts, roundsPerLogicalOp, threshold, prefactor [per block per syndrome cycle], logicalErrorExponent [= d_circ/2], source URLs).

Inferred read-only

get_historic_series

Return the full historic time series — either two-qubit gate error rates ("fidelity") or physical qubit counts ("qubit-count") — broken down by hardware type.

Inferred read-only

get_agent_brief

Return the plain-text site brief describing scope, assumptions, the honesty clause, and the API contract.

Inferred read-only
