Trait roqoqo::operations::OperatePragmaNoise

pub trait OperatePragmaNoise: Operate + InvolveQubits + Substitute + Clone + PartialEq + OperatePragma + SupportedVersion {
    // Required methods
    fn superoperator(&self) -> Result<Array2<f64>, RoqoqoError>;
    fn powercf(&self, power: CalculatorFloat) -> Self;
}

Trait for PRAGMA Operations that are not necessary available on all universal quantum hardware, that indicate noise.

Example

use ndarray::{array, Array2};
use roqoqo::operations::{OperatePragmaNoise, OperatePragmaNoiseProba, PragmaDamping};
use qoqo_calculator::CalculatorFloat;

let pragma = PragmaDamping::new(0, CalculatorFloat::from(0.005), CalculatorFloat::from(0.02));

// 1) The superoperator representation of the noise Pragma
let superop_prob: f64 = *pragma.probability().float().unwrap();
let superop_sqrt: f64 = (1.0 - superop_prob.clone()).sqrt();
let superop: Array2<f64> = array![
    [1.0, 0.0, 0.0, superop_prob.clone()],
    [0.0, superop_sqrt, 0.0, 0.0],
    [0.0, 0.0, superop_sqrt, 0.0],
    [0.0, 0.0, 0.0, 1.0 - superop_prob.clone()],
];
assert_eq!(superop, pragma.superoperator().unwrap());
// 2) The power function applied to the noise Pragma
let pragma_test = PragmaDamping::new(
    0,
    CalculatorFloat::from(0.005 * 1.5),
    CalculatorFloat::from(0.02),
);
assert_eq!(pragma_test, pragma.powercf(CalculatorFloat::from(1.5)));

Required Methods

fn superoperator(&self) -> Result<Array2<f64>, RoqoqoError>

Returns superoperator matrix of the Operation.

fn powercf(&self, power: CalculatorFloat) -> Self

Returns the gate to the power of power.
