Generator a random DensityMatrix.

প্যারামিটার

• dims (int or tuple) -- the dimensions of the DensityMatrix.

• rank (int or None) -- Optional, the rank of the density matrix. The default value is full-rank.

• method (string) -- Optional. The method to use. 'Hilbert-Schmidt': (Default) sample from the Hilbert-Schmidt metric. 'Bures': sample from the Bures metric.

• seed (int or np.random.Generator) -- Optional. Set a fixed seed or generator for RNG.
