qoqo.operations.PragmaGetPauliProduct

class qoqo.operations.PragmaGetPauliProduct

This PRAGMA measurement operation returns a Pauli product expectation value.

This PRAGMA operation returns a Pauli product expectation value after applying a Rotate to another basis. It performs all of the operation on a clone of the quantum register, sothat the actual quantum register remains unchanged.

Parameters:

qubit_paulis (dict[int, int]) – The dictionary of the pauli matrix to apply to each qubit in the form {qubit: pauli}. Allowed values to be provided for ‘pauli’ are: 0 = identity, 1 = PauliX, 2 = PauliY, 3 = PauliZ.
readout (string) – The name of the classical readout register.
circuit (Circuit) – The measurement preparation Circuit, applied on a copy of the register before measurement.
