cirq.measure_confusion_matrix
Prepares TensoredConfusionMatrices
for the n qubits in the input.
cirq.measure_confusion_matrix(
sampler: 'cirq.Sampler',
qubits: Union[Sequence['cirq.Qid'], Sequence[Sequence['cirq.Qid']]],
repetitions: int = 1000
) -> cirq.TensoredConfusionMatrices
The confusion matrix (CM) for two qubits is the following matrix:
⎡ Pr(00|00) Pr(01|00) Pr(10|00) Pr(11|00) ⎤
⎢ Pr(00|01) Pr(01|01) Pr(10|01) Pr(11|01) ⎥
⎢ Pr(00|10) Pr(01|10) Pr(10|10) Pr(11|10) ⎥
⎣ Pr(00|11) Pr(01|11) Pr(10|11) Pr(11|11) ⎦
where Pr(ij | pq) = Probability of observing “ij” given state “pq” was prepared.
