Struct roqoqo::noise_models::DecoherenceOnGateModel

pub struct DecoherenceOnGateModel {
    single_qubit_gate_errors: HashMap<(String, usize), PlusMinusLindbladNoiseOperator>,
    two_qubit_gate_errors: HashMap<(String, (usize, usize)), PlusMinusLindbladNoiseOperator>,
    three_qubit_gate_errors: HashMap<(String, (usize, usize, usize)), PlusMinusLindbladNoiseOperator>,
    multi_qubit_gate_errors: HashMap<(String, Vec<usize>), PlusMinusLindbladNoiseOperator>,
}

Error model for noise that is only present on gate executions.

Adds additional noise when specific gates (identified by hqslang name and qubits acted on) are executed. The noise is given in the form of a struqture::spins::PlusMinusLindbladNoiseOperator the same way it is for the ContinuousDecoherence model. Example:

use roqoqo::noise_models::DecoherenceOnGateModel;
use struqture::spins::{PlusMinusLindbladNoiseOperator, PlusMinusProduct};
use struqture::prelude::*;

let mut noise_model = DecoherenceOnGateModel::new();
let mut lindblad_noise = PlusMinusLindbladNoiseOperator::new();
lindblad_noise.add_operator_product(
   (PlusMinusProduct::new().z(0), PlusMinusProduct::new().z(0)),
   0.9.into(),).unwrap();
lindblad_noise.add_operator_product(
   (PlusMinusProduct::new().z(1), PlusMinusProduct::new().z(1)),
   0.9.into(),).unwrap();

noise_model = noise_model.set_two_qubit_gate_error(
"CNOT", 0,1,
lindblad_noise
);
