Struct roqoqo::operations::PragmaSetStateVector [−][src]
Expand description
This PRAGMA Operation sets the statevector of a quantum register.
The Circuit() module automatically initializes the qubits in the |0> state, so this PRAGMA operation allows you to set the state of the qubits to a state of your choosing.
Example
For instance, to initialize the $|\Psi^->$ Bell state, we pass the following statevec
to
the PragmaSetStateVector operation.
use ndarray::{array, Array1};
use num_complex::Complex64;
use roqoqo::operations::PragmaSetStateVector;
let statevec: Array1<Complex64> = array![
Complex64::new(0.0, 0.0),
Complex64::new(1.0 / (2.0_f64).sqrt(), 0.0),
Complex64::new(-1.0 / (2.0_f64).sqrt(), 0.0),
Complex64::new(0.0, 0.0)
];
let pragma = PragmaSetStateVector::new(statevec.clone());
Fields
statevector: Array1<Complex64>
The statevector that is initialized.

The inverse inclusion map: attempts to construct self
from the equivalent element of its
superset. Read more
pub fn is_in_subset(&self) -> bool
pub fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
pub fn to_subset_unchecked(&self) -> SS
pub fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
pub fn from_subset(element: &SS) -> SP
pub fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
