Result.get_counts(experiment=None)

Get the histogram data of an experiment.

Parameters

experiment (str or QuantumCircuit or Schedule or int or None) – the index of the experiment, as specified by get_data().

Returns

int] or list[dict[str:int]]: a dictionary or a list of

dictionaries. A dictionary has the counts for each qubit with the keys containing a string in binary format and separated according to the registers in circuit (e.g. 0100 1110). The string is little-endian (cr[0] on the right hand side).

Return type

dict[str

Raises

QiskitError – if there are no counts for the experiment.
