Struct LayoutScore 

Source 
pub struct LayoutScore {
    pub total: f64,
    pub distance: f64,

Expand description

Breakdown of one layout score.

Component fields are unweighted by the objective, but include the logical interaction weights already present in the circuit analysis. The LayoutScore::total field applies the objective weights.

Fields§

§total: f64

Weighted sum according to LayoutObjective.

§distance: f64

Raw weighted-distance component.

§direction: f64

Raw direction-mismatch component.

§two_qubit_error: f64

Unweighted effective two-qubit placement cost.

In addition to known gate-specific error probabilities, this includes a conservative 1.0 cost for native gates that are unsupported or lack calibration on the selected physical edge. The value is accumulated over weighted logical interactions and may exceed 1.0; it is not a measured error rate and must not be used for calibration reporting or circuit-success estimation.

§readout_error: f64

Raw readout error component.

§used_fidelity: bool

Whether the objective was configured to use fidelity terms.
