quri_parts.core.sampling package#

MeasurementCounts#

MeasurementCounts represents count statistics of repeated measurements of a quantum circuit. Keys are observed bit patterns encoded in integers and values are counts of observation of the corresponding bit patterns.

alias of Mapping[int, Union[int, float]]

ConcurrentSampler#

ConcurrentSampler represents a function that samples specified (non-parametric) circuits concurrently.

alias of Callable[[Iterable[tuple[NonParametricQuantumCircuit, int]]], Iterable[Mapping[int, Union[int, float]]]]

PauliSamplingShotsAllocator#

PauliSamplingShotsAllocator represents a function that distributes a given number of sampling shots to each CommutablePauliSet.

alias of Callable[[Operator, Collection[Set[PauliLabel]], int], Collection[PauliSamplingSetting]]

WeightedSamplingShotsAllocator#

WeightedSamplingShotsAllocator represents a function that distributes a given number of sampling shots based on a set of weights.

alias of Callable[[Sequence[complex], int], Sequence[int]]
