Struct WireMap 

pub struct WireMap { /* private fields */ }

Bidirectional mapping between PennyLane wire labels and qubit indices.

PennyLane uses zero-based integer wires by default. When a circuit uses wires [0, 1, 2, ...] (dense mapping) the WireMap is trivial. Non-contiguous or string-labelled wires must be remapped to a contiguous qubit range before simulation.

Implementations

impl WireMap

pub fn from_wires(wires: &[usize]) -> Self

Build a wire map from a sorted list of unique wire indices.

Wire wires[i] maps to qubit i.

pub fn wire_to_qubit(&self, wire: usize) -> Option<QubitId>

Map a PennyLane wire index to a QuantRS2 QubitId.

pub fn qubit_to_wire(&self, qubit: u32) -> Option<usize>

Map a QuantRS2 qubit index back to a PennyLane wire index.

pub fn num_wires(&self) -> usize

Total number of wires (= total number of qubits).
