Struct SurfaceCodeLayout 

pub struct SurfaceCodeLayout {
    pub data_qubits: Vec<QubitIndex>,
    pub x_ancillas: Vec<QubitIndex>,
    pub z_ancillas: Vec<QubitIndex>,
    pub x_stabilizers: Vec<Vec<QubitIndex>>,
    pub z_stabilizers: Vec<Vec<QubitIndex>>,
}

Physical layout of a surface code: which data qubits participate in each stabilizer, and the ancilla qubit assigned to each stabilizer.

Fields

data_qubits: Vec<QubitIndex>

Indices of data qubits.

x_ancillas: Vec<QubitIndex>

Indices of X-type (plaquette) ancilla qubits.

z_ancillas: Vec<QubitIndex>

Indices of Z-type (vertex) ancilla qubits.

x_stabilizers: Vec<Vec<QubitIndex>>

For each X stabilizer, the data qubits it acts on.

z_stabilizers: Vec<Vec<QubitIndex>>

For each Z stabilizer, the data qubits it acts on.

Implementations

impl SurfaceCodeLayout

pub fn distance_3() -> Self

Create the layout for a distance-3 rotated surface code.

Total qubits: 9 data (indices 0..8) + 4 X-ancillas (9..12) + 4 Z-ancillas (13..16) = 17.

pub fn total_qubits(&self) -> u32

Total number of physical qubits (data + ancilla).

pub fn num_stabilizers(&self) -> usize

Total number of stabilizers (X + Z).
