docs: For this program define a classical bit flip readout error channel parametrized by
          ``p00`` and ``p11``. This models the effect of thermal noise that corrupts the readout
          signal **after** it has interrogated the qubit.
  
          :param int|QubitPlaceholder qubit: The qubit with noisy readout.
          :param float p00: The probability of obtaining the measurement result 0 given that the qubit
            is in state 0.

            is in state 1.
