  • 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.
