random_hermitian(dims, traceless=False, seed=None)

Return a random hermitian Operator.

The operator is sampled from Gaussian Unitary Ensemble.

Parameters

• dims (int or tuple) – the input dimension of the Operator.
• traceless (bool) – Optional. If True subtract diagonal entries to return a traceless hermitian operator (Default: False).
• seed (int or np.random.Generator) – Optional. Set a fixed seed or generator for RNG.

Returns

a Hermitian operator.
