iqm.benchmarks.coherence.coherence.calculate_probabilities(counts: dict[str, int], nqubits: int, coherence_exp: str) → Tuple[List[float], int]

Calculate the number of times ‘0’ was measured for each qubit based on the provided counts.

Parameters:

• counts (dict[str, int]) – A dictionary where keys are bitstrings representing measurement outcomes and values are the counts of those outcomes.

• nqubits (int) – The number of qubits being measured.

• coherence_exp (str) – A string indicating the coherence experiment type (‘t1’ or other).

Returns:

A tuple containing:

• A list of occurrences of measuring ‘0’ for each qubit.

• The total number of shots (measurements).

Return type:

tuple
