InteractionGraph

cqlib_core::compile::transform::layout

Struct InteractionGraph 

Source 
pub struct InteractionGraph { /* private fields */ }
Expand description

Weighted logical interaction graph.

The graph stores one edge per unordered logical-qubit pair. Edges are kept sorted by endpoint, which makes downstream algorithms reproducible without relying on hash-map iteration order.

Implementations§

Source§

impl InteractionGraph

Source

pub fn new() -> Self

Creates an empty interaction graph.

Source

pub fn interactions(&self) -> &[Interaction]

Returns all interactions in deterministic endpoint order.

Source

pub fn is_empty(&self) -> bool

Returns whether no two-qubit interactions were observed.

Source

pub fn len(&self) -> usize

Returns the number of logical interaction edges.

Source

pub fn logical_activity(&self) -> BTreeMap<LogicalQubit, f64>

Returns per-logical-qubit activity weight from incident interactions.

Activity is used to place busier logical qubits earlier, and to scale readout-error scoring when calibration data is available.
