-
CTMPExpvalMeasMitigator.generator_matrix(qubits=None)[source]¶ Return the generator matrix on the specified qubits.
The generator matrix \(G\) is given by \(\sum_i r_i G_i\) where the sum is taken over all \(G_i\) acting on the specified qubits subset.
- Parameters
qubits (
Optional[List[int]]) – Optional, qubit subset for the generators.- Returns
the generator matrix \(G\).
- Return type
