abstract BaseReadoutMitigator.quasi_probabilities(data, qubits=None, clbits=None, shots=None)

Convert counts to a dictionary of quasi-probabilities

Paramètres

• data (Counts) – Counts to be mitigated.

• qubits (Optional[Iterable[int]]) – the physical qubits measured to obtain the counts clbits. If None these are assumed to be qubits [0, …, N-1] for N-bit counts.

• clbits (Optional[List[int]]) – Optional, marginalize counts to just these bits.

• shots (Optional[int]) – Optional, the total number of shots, if None shots will be calculated as the sum of all counts.

A dictionary containing pairs of [output, mean] where « output »

is the key in the dictionaries, which is the length-N bitstring of a measured standard basis state, and « mean » is the mean of non-zero quasi-probability estimates.
