bitflip_expval(generators, params, ops)

Compute expectation value for the Bitflip noise model.

Parameters:

• generators (ArrayLike) – Binary matrix of shape (n_generators, n_qubits).

• params (ArrayLike) – Error probabilities/parameters $ heta$.

• ops (ArrayLike) – Binary matrix representing Pauli Z operators.

Returns:

A tuple containing:

• Expectation values.

• A zero array for standard error (since this is analytical).

Return type:

tuple[jnp.ndarray, jnp.ndarray]
