quri_parts.core.measurement.interface module¶

PauliMeasurementCircuitGeneration¶

PauliMeasurementCircuitGeneration represents a function that generates a circuit (a gate list) for measuring mutually commuting Pauli operators.

alias of Callable[[Set[PauliLabel]], Sequence[QuantumGate]]

PauliReconstructor¶

PauliReconstructor represents a function that reconstructs a value of a Pauli operator from a measurement result of its measurement circuit.

alias of Callable[[int], int]

PauliReconstructorFactory¶

PauliReconstructorFactory represents a factory function that returns a PauliReconstructor for a given Pauli operator.

alias of Callable[[PauliLabel], Callable[[int], int]]

class CommutablePauliSetMeasurement(*args, **kwargs)¶

Bases: Protocol

Represents a measurement scheme for a set of commutable Pauli operators.

abstract property pauli_set: core.operator.pauli.CommutablePauliSet¶: A set of commutable Pauli operators subject to the measurement.

abstract property measurement_circuit: Sequence[QuantumGate]¶: A circuit required to measure the given commutable Pauli operators at once.

abstract property pauli_reconstructor_factory: core.measurement.interface.PauliReconstructorFactory¶: A factory of PauliReconstructor that reconstructs a value of a Pauli operator from a measurement result of the measurement circuit.

class CommutablePauliSetMeasurementTuple(pauli_set, measurement_circuit, pauli_reconstructor_factory)¶

Bases: NamedTuple

Parameters:

pauli_set (core.operator.pauli.CommutablePauliSet)
measurement_circuit (Sequence[QuantumGate])
pauli_reconstructor_factory (core.measurement.interface.PauliReconstructorFactory)

pauli_reconstructor_factory: PauliReconstructorFactory¶: Alias for field number 2

CommutablePauliSetMeasurementFactory¶

Represents a function that performs grouping of Pauli operators into sets of commutable Pauli operators and returns measurement schemes for them.
