Struct Toffoli 

pub struct Toffoli;

Defines a Toffoli operator.

A three-qubit operator that flips the target qubit if both control qubits are in the |1> state. Also known as CCNOT (Controlled-Controlled-NOT).

Trait Implementations

impl Clone for Toffoli

fn clone(&self) -> Toffoli

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Toffoli

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

Formats the value using the given formatter.

impl Display for Toffoli

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

Formats the value using the given formatter.

impl Operator for Toffoli

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

Applies the Toffoli operator to the given state’s target qubit, using the control qubits.

Arguments:

• state - The state to apply the operator to.

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

• control_qubits - The control qubits for the operator. This should be two qubits.

Returns:

• The new state after applying the Toffoli operator.

Errors:

• Error::InvalidNumberOfQubits - If the target or control qubits are not 1 and 2 respectively, or if the control qubits are not different.

• Error::InvalidQubitIndex - If the target or control qubit indices are 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.

fn to_compilable(&self) -> Option<&dyn Compilable>

Optionally returns an intermediate representation of the operator for compilation to OpenQASM.
