Struct roqoqo::operations::PragmaGetPauliProduct

pub struct PragmaGetPauliProduct {
    qubit_paulis: HashMap<usize, usize>,
    readout: String,
    circuit: Circuit,
}

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, so that the actual quantum register remains unchanged.

Fields

qubit_paulis: HashMap<usize, usize>

The HashMap 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.
