Struct LayerwiseConfig 

pub struct LayerwiseConfig {
    pub n_qubits: usize,
    pub target_depth: usize,
    pub iters_per_stage: usize,
    pub lr: f32,
    pub seed_noise: f32,
}

Configuration for layer-wise warm-start VQE training.

Fields

n_qubits: usize

Number of qubits in the ansatz.

target_depth: usize

Final ansatz depth to grow to (number of entangling layers).

iters_per_stage: usize

Parameter-shift gradient-descent iterations spent at each depth stage.

lr: f32

Learning rate for gradient descent.

seed_noise: f32

Small std-dev for randomizing the very first (depth-0) layer; the grown layers are always zero-initialized to preserve the identity-block warm start, so only the seed layer needs symmetry breaking.

Implementations

impl LayerwiseConfig

pub fn new( n_qubits: usize, target_depth: usize, iters_per_stage: usize, lr: f32, seed_noise: f32, ) -> QuantumResult<Self>

Validate the configuration.

Errors

Returns QuantumError::InvalidParameter / QuantumError::InvalidQubitCount for non-positive qubit counts, zero iterations, or a non-finite learning rate.

Trait Implementations

impl Clone for LayerwiseConfig

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayerwiseConfig

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

Formats the value using the given formatter.
