Struct PhaseShift

pub struct PhaseShift { /* private fields */ }

Defines the phase shift operator

A single-qubit operator that applies a phase shift of the provided angle to the |1> state. Also known as the phase shift gate.

Implementations

impl PhaseShift

pub fn new(angle: f64) -> Self

Creates a new PhaseShift operator with the given angle.

Arguments:

• angle - The angle of the phase shift in radians.

Trait Implementations

impl Clone for PhaseShift

fn clone(&self) -> PhaseShift

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PhaseShift

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

Formats the value using the given formatter.

impl Operator for PhaseShift

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

Applies the phase shift 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 phase shift operator.

Errors:

• Error::InvalidNumberOfQubits - If the target qubits is not 1.

• Error::InvalidQubitIndex - If the target qubit index or control qubit index is invalid for the number of qubits in the state.

• Error::OverlappingControlAndTargetQubits - If the control qubit and target qubit indices overlap.

fn base_qubits(&self) -> usize

Returns the number of qubits that the operator acts on.
