Fields

name: String

Name shown in backend queries

max_qubits: usize

Number of available qubits

max_shots: usize

Maximum shots per job

latency_ms: u64

Simulated job queue latency in milliseconds

error_rate: f64

Depolarizing error rate per gate (0.0 = perfect)

fail_rate: f64

Probability that a job fails (for testing error handling)

gate_set: Vec<String>

Supported gate names (empty = all gates supported)

connectivity: Vec<(usize, usize)>

Allowed qubit pairs for 2-qubit gates (empty = all pairs allowed)

rng_seed: u64

Random seed for reproducible results

Implementations

impl MockBackendConfig

pub fn perfect(n_qubits: usize) -> Self

Create a “perfect” noiseless backend with the given qubit count.

pub fn ibm_nairobi_like() -> Self

Create a backend mimicking IBM Nairobi (7 qubits, T-topology).

pub fn always_fails() -> Self

Create a backend that always fails — useful for testing error-handling paths.

pub fn with_noise(n_qubits: usize, error_rate: f64) -> Self

Create a noisy backend with the given error rate.
