Enum Pauli 

pub enum Pauli {
    X,
    Y,
    Z,
}

Defines the Pauli operators: X, Y, Z.

Variants

X

Pauli-X operator (NOT gate)

Y

Pauli-Y operator

Z

Pauli-Z operator

Implementations

impl Pauli

pub fn to_pauli_string(&self, target_qubit: usize) -> PauliString

Returns the Pauli string representation of the operator.

Returns

• A Pauli string with the specified Pauli operator on the target qubit and a coefficient of 1.0.

Trait Implementations

impl Clone for Pauli

fn clone(&self) -> Pauli

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pauli

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

Formats the value using the given formatter.

impl Display for Pauli

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

Formats the value using the given formatter.

impl Operator for Pauli

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

Applies the Pauli 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 Pauli operator.

Errors:

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

• Error::InvalidQubitIndex - If the target 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.

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

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

impl PartialEq for Pauli

fn eq(&self, other: &Pauli) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
