qiskit.opflow.primitive_ops.Z2Symmetries.taper_clifford

Z2Symmetries.taper_clifford(operator)[source]

This method operates the second part of the tapering. This function assumes that the input operators have already been transformed using convert_clifford(). The redundant qubits due to the symmetries are dropped and replaced by their two possible eigenvalues. The tapering_values will be stored into the resulted operator for a record.
