random_clifford(num_qubits, seed=None)

Return a random Clifford operator.

The Clifford is sampled using the method of Reference [1].

Parameters

• num_qubits (int) – the number of qubits for the Clifford
• seed (int or np.random.Generator) – Optional. Set a fixed seed or generator for RNG.

Returns

a random Clifford operator.

Return type

Clifford
