random_support(tableau, return_support=False)#

Compute the number of bits over which the stabilizer state corresponding to this stim tableau would have measurement outcomes which are random.

Parameters:

  • tableau (Union[stim.Tableau, stim.TableauSimulator]) – stim.Tableau corresponding to the stabilizer state we want the random support for.

  • return_support (bool, optional (default False)) – If True also returns a list of qubit indices over which the distribution of outcome bit strings is random.

Returns:

  • num_random (int) – Number of bit on which stabilize state is random.

  • support (list of bool) – A list of boolean values which can be used as a bitmask and corresponds to the bits found to be random.
