Struct Unitary2

pub struct Unitary2 { /* private fields */ }

An arbitrary 2×2 unitary operator.

This operator can be applied to a single qubit in a quantum state. It is represented by a 2×2 unitary matrix.

Implementations

impl Unitary2

pub fn new(matrix: [[Complex<f64>; 2]; 2]) -> Result<Self, Error>

Creates a new Unitary2 operator with the given 2×2 unitary matrix.

Arguments:

• matrix - A 2×2 unitary matrix represented as a 2D array of complex numbers.

Returns:

• Result<Self, Error> - A result containing the new Unitary2 operator or an error if the matrix is not unitary.

Errors:

• Error::NonUnitaryMatrix - If the provided matrix is not unitary.

Trait Implementations

impl Clone for Unitary2

fn clone(&self) -> Unitary2

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Unitary2

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Operator for Unitary2

fn apply( &self, state: &State, target_qubits: &[usize], control_qubits: &[usize], ) -> Result<State, Error>

Applies the Unitary2 operator to the given state’s target qubit.

Arguments:

• state - The state to apply the operator to.

• target_qubits - The target qubits to apply the operator to. This should be a single qubit.

• control_qubits - The control qubits for the operator. If not empty, the operator will be applied conditionally based on the control qubits. Otherwise, it will be applied unconditionally.

Returns:

• The new state after applying the Unitary2 operator.

fn base_qubits(&self) -> usize

Returns the number of qubits that the operator acts on.
