Implementations

impl DeviceTopology

pub fn linear_chain(num_qubits: usize) -> Self

Create a linear chain topology

pub fn square_lattice(width: usize, height: usize) -> Self

Create a square lattice topology

pub fn heavy_hex(distance: usize) -> Self

Create IBM heavy-hex topology

pub fn get_neighbors(&self, qubit: usize) -> Vec<usize>

Get nearest neighbors of a qubit

pub fn distance(&self, qubit1: usize, qubit2: usize) -> f64

Calculate distance between two qubits

Trait Implementations

impl Clone for DeviceTopology

fn clone(&self) -> DeviceTopology

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceTopology

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

Formats the value using the given formatter.

impl Default for DeviceTopology

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DeviceTopology

fn eq(&self, other: &DeviceTopology) -> 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.
