mqt.core.bench.qft¶

QFT benchmark instances and options.

Module Contents¶

class Method¶

Bases: enum.Enum

Full-register or semiclassical measurement-and-feed-forward method.

STANDARD = 0¶

SEMICLASSICAL = 1¶

class Options(*, qubits: int, period_exponent: int, method: Method = Method.STANDARD)¶

Parameters for a QFT benchmark.

property qubits: int¶: The number of transformed qubits.

property period_exponent: int¶: The exponent \(k\) of the input period \(2^k\).

property method: Method¶: The circuit method.

class QFT(options: Options)¶

A validated QFT benchmark.

property options: Options¶: The resolved benchmark parameters.

property output: Output¶: The logical output register.

probability(outcome: str) → float¶: Return the ideal probability of an outcome.

evaluate(counts: Mapping[str, int]) → Evaluation¶: Compare sampled counts with the ideal distribution.

generate() → QCProgram¶: Generate the benchmark as a QC program.

property instance_specification_json: str¶: The canonical instance specification JSON.

property manifest_json: str¶: The canonical manifest JSON.

property case_id: str¶: The stable semantic case ID.

static from_instance_specification_json(json: str, *, source: str = '<instance-specification>') → QFT¶: Parse a strict benchmark instance specification.

static from_manifest_json(json: str, *, source: str = '<manifest>') → QFT¶: Parse a strict benchmark manifest.
