Struct SWAP

pub struct SWAP;

Defines a SWAP operator.

A two-qubit operator that swaps the states of the two qubits.

Trait Implementations

impl Clone for SWAP

fn clone(&self) -> SWAP

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SWAP

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

Formats the value using the given formatter.

impl Operator for SWAP

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

Applies the SWAP operator to the given state’s target qubits.

Arguments:

• state - The state to apply the operator to.

• target_qubits - The target qubits to apply the operator to. This should be two qubits.

• control_qubits - The control qubits. If empty, the swap is unconditional. Otherwise, the swap occurs only if all control qubits are |1> for the relevant basis states.

Returns:

• The new state after applying the SWAP operator.

Errors:

• Error::InvalidNumberOfQubits - If the target qubits are not 2 different qubits.

• Error::InvalidQubitIndex - If the target qubit indices are invalid for the number of qubits in the state.

• Error::InvalidQubitIndex - If the target qubit indices are not different.

• 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.
