docs: r"""Returns a AsymmetricDepolarizingChannel with given parameter.
  
      This channel evolves a density matrix via
  
          $$
          \rho \rightarrow (1 - p_x - p_y - p_z) \rho

      Args:
          p_x: The probability that a Pauli X and no other gate occurs.
          p_y: The probability that a Pauli Y and no other gate occurs.
          p_z: The probability that a Pauli Z and no other gate occurs.
  
      Raises:
          ValueError: if the args or the sum of the args are not probabilities.
