class loom.cliffordsim.data_store.DataStore[source]

Bases: object

An Object that records relevant information users might want recorded from a particular computation.

get_pframe_measurements(pauliframe_id)[source]

Helper function to aggregate all measurement results belonging to the same Pframe. The keys of returned dict are the uuids of meausurements in the circuit.

Returns:: A dictionary where keys are measurement ids and values are the PauliFrame flip results for the given Pframe id.
Return type:: dict

get_pframes(temporal_direction='forward')[source]

A helper function to return a tuple of all Pframes (dict)

temporal_direction can be either “forward” or “backward”.

Returns:: A tuple of dictionaries, where each dictionary corresponds to a PauliFrame that was created in the circuit, and the computed output — for frames propagated forwards.
Return type:: tuple

record_classical_register(input_classical_reg)[source]

Records the Snapshot of the Classical Register into the DataStore.

Return type:: None

record_measurement_from_pauliframes(measurement_id, results, init_pauliframes)[source]

Records measurement flips that result from the interaction of Pauli frames and measurement operations.

Measurement flips is passed as a list as there could be multiple Pframes.

Return type:: None

record_measurements(measurement_id, measurement_result, is_result_random)[source]

Records the measurement result in the DataStore. Raises a ValueError if no time step was found in the Moment.

Return type:: None

record_pauli_frame(init_pauliframe, recorded_pauliframe)[source]

Records the PauliFrame in the DataStore. Raises a ValueError if no time step was found in the Moment.

Return type:: None

set_time_step(time_step)[source]

Sets the time step of the current Moment being processed.

Return type:: None
